NCR PDISP-158 Tabular Output Consolidation and Water items are not needed in the Output Explorer as they are already printed in the Analysis Options. Build 6
NCR PDISP-157 Soil column displacements Soil column displacements' view crashes when dealing with files having non-linear curves. Build 5
NCR PDISP-156 Analysis The vertical stress at any point that is at the load level and in the loaded area should be equal to the pressure specified at that load. Build 5
NCR PDISP-145 Miscellaneous It would be useful if PDisp remembered the location of the last opened file, and presented it when next performing File->Open. Build 5
NCR PDISP-144 Miscellaneous PDisp would better save backup files to the user's AppData\Local\Temp folder, rather than the Program Files\Samples folder since users may not always have write permissions to the latter. They should also be deleted on closing the data file. Build 5
NCR PDISP-142 UI, Analysis Pdisp is crashing when a file with wrong input in Analysis options dialog is analysed. Build 5
NCR PDISP-141 UI, Analysis Pdisp crashes when analysing a model that has 0 number of rectangles specified for a circular load. Build 5
NCR PDISP-140 UI, Analysis Pdisp may crash if an analysis is attempted with no displacement points, lines or grids. Build 5
NCR PDISP-138 UI If non units of length are not metres, and loads are rotated, then their rotations (and so results) may not be as expected. Build 5
NCR PDISP-119 Input Pdisp misbehaves if Youngs Modulus of zero is set for either or both top and bottom of strata. Build 5
NCR PDISP-104 Input, Soil Profiles Double-clicking the "Colour" field in a soil profile's table opens the colour dialog but without the correct colour shown. So it is intedeterminable by the user. Build 5
NCR PDISP-101 UI, Graphs The title bar of line graphs shows only the file extension ".pdd" and not the full file name. Build 5

19.3 Minor Enhancements
Item Category Description Status
ME PDISP-130 Miscellaneous Update to licensing. Build 16
ME PDISP-118 Tabular Output, Validation The alignment of warnings in the Tabular Output is poor. It would also benefit from numbering there and in the Analysis Dialog. Build 13
ME PDISP-112 Tabular Output, Validation Warning added to Tabular Output if horizontal displacements are requested and the "stiffness at displacement point" option is selected. (Same warning as has previously appeared only on exiting the Analysis Options dialog.) Build 11
ME PDISP-94 Miscellaneous Additions/amendments to feature logging e.g. for possible future UX improvements (e.g. graphics labelling subsets, delete results button, Tabular Output Wizard "All" and "None" buttons, graphics filled polygons, use of circular loads, rotated rectangular loads, printing of graphics or tabular output), use of calculation sheet. Build 8
ME PDISP-92 Validation, Displacement Data Removal of warning in Displacement Data table re >99 intervals to prevent possible repetitive warning. Moved to pre-analysis checks. Build 8
ME PDISP-90 Validation The Analysis Options dialog warns repeatedly (and unnecessarily) if the global poisson's ratio is less than poisson's ratios in soil profiles. Only one warning is necessary. (Item includes improvement to text of warning message.) Build 8
ME PDISP-88 2D Plan Filled contours can only be activated in the Plan View when line contours are already selected. This is an unnecessary restriction. Build 8
ME PDISP-87 Validation Error message re rigid boundary level would better point the user at the Analysis Options dialog for resolution. Build 8
ME PDISP-86 UI, Table Views Table View headers tidied up (consistency of units row to all tables with units, removal of unnecessary blank lines in headers) (inc blank line in header of soil zones' table). Build 8
ME PDISP-85 Tabular Output, 2D Plan, Graphical Input Condensed font droplist, with improved flexibility re scaling, to Pdisp toolbar for use by Plan View, Graphical Input View and Tabular Output in place of previous 2-size condensed font options. Build 8
ME PDISP-84 Tabular Output Inform user that Tabular Output "is being prepared. Please wait." in case the lack of information causes them to feel the program has crashed. Build 8
ME PDISP-82 Toolbars Some toolbar icons differ from Xdisp, whose icons have been updated in a recent revision. It would be more helpful to users of both programs to present consistent icons. Build 8
ME PDISP-81 Gateway Move non-linear curves branch of Gateway below Soil Profiles (and introduce GSA Piled Raft Data as super-title to its data). Build 8
ME PDISP-80 Analysis Options Move Soil Boundary Layer to top of/higher in Analysis Options dialog. Build 8
ME PDISP-75 Validation, Table Views Improved (less obtrusive) data validation in table views. Some validation delayed to pre-analysis check. Build 8
ME PDISP-72 3D Graphics The 3D Graphics Settings should more helpfully default to a wire frame view since load and displacement data is then visible. Build 8
ME PDISP-69 Import Import of Xdisp files (insofar as is possible i.e. displacement data, background data, restuls and imported results). Build 8
ME PDISP-62 Miscellaneous Writing 19.2 files (for GSA use) from 19.3. Build 8
ME PDISP-61 3D Graphics The 3D Graphics Settings Wizard (Displacements' page) is unusable when large numbers of imported displacements are available. Build 8
ME PDISP-59 Miscellaneous "Application Look", on the program's View menu, does not work well for all styles. Unnecessary option added for Pdisp 19.3. Remove. Build 8
ME PDISP-56 UI, Polygonal Loads Move Wizard column to start of polygon loads columns. Build 8
ME PDISP-55 UI Do not present page set up dialog after analysing (and set all check boxes to true by default when it is opened). Build 8
ME PDISP-54 Tabular Output, 3DGraphics 3D Graphics: Removal of titles and warning re comparison of Mindlin v Boussinesq (moved to Analysis Dialog and Tabular Output). Build 8
ME PDISP-53 Tabular Output The title of the Tabular Output wizard ("Page Setup") is misleading. Change to e.g. "Tabular Output Selection". Build 8
ME PDISP-52 3DGraphics The 3D Graphics View does not preserve results' selections (where might be appropriate) if data is amended, results deleted, and an analysis re-run. Build 8
ME PDISP-51 UI The Analysis Options FormView may open with some content/buttons accessible only by scrolling. Build 8
ME PDISP-44 Import Import Xdisp data file (but displacement data only to Xdisp version 19.3). Build 8
ME PDISP-41 Graphics, Results, Displacement Lines Inclined displacement lines are not shown in the Plan View, so their line graphs of results cannot be selected and shown. Build 8
ME PDISP-67 Installer Revision to digital signature of installer. Build 6
ME PDISP-31 Results, Import User-defined tolerance for omission of duplicate locations on import and export of CSV results. Build 5
19.3 Fixes
Item Category Description Status
NCR PDISP-129 UI, Displacement Data If the "Name" field of displacement data is edited, the change may not be preserved upon saving and reopening the data file. Build 15
NCR PDISP-128 Reading Pdisp may skip reading some modules (e.g. soil zones) if a file which has imported displacements is opened. Build 14
NCR PDISP-127 Polygonal Loads, Input Pdisp may fail to preserve polygonal load coordinates when the loads table is closed and/or the file saved. Build 13
NCR PDISP-126 Polygonal Loads, Analysis Pdisp crashes if an analysis is attempted with a polygonal load which has no polygon coordinates. Build 13
NCR PDISP-123 Polygonal Loads Performing an "update" when batch testing a file which contains a polygonal load results in the polygonal load being saved as its set of rectangular loads that are used for analysis. The polygonal loads are lost. Build 13
NCR PDISP-122 Tabular Output The Tabular Output is not updated after making changes in its wizard. Build 13
NCR PDISP-121 Tabular Output Results pertaining to the 0th index of a level array are being printed twice in the "full" version of the Tabular Output. Build 13
NCR PDISP-120 Miscellaneous Licensing fix (commercial builds only). Build 12
NCR PDISP-115 Tabular Output Switching from "Condensed" to "Full" in the Tabular Output has no effect. Build 11
NCR PDISP-114 Warnings Checks for warnings are not completed before analysis if the Mindlin method is chosen without the legacy option e.g. displacement and load location checks are skipped (among others). Build 11
NCR PDISP-113 Tabular Output Analysis options are not all reported in the Tabular Output. Build 11
NCR PDISP-111 Analysis If horizontal displacements/loads are specified, and the model contains overlapping soil zones or gaps in soil zones, then Pdisp may calculate incorrect results. Build 11
NCR PDISP-110 Analysis If non-SI units are used for length (i.e. not metres), then Pdisp fails to display, in the polygonal load's wizard, the rectangles by which a polygonal load will be approximated. Build 11
NCR PDISP-109 UI Pdisp crashes when the coordinates wizard for a polygonal load is closed if that wizard was opened from an incomplete row in the loads table. Build 11
NCR PDISP-108 2D Plan "Set contour interval" is greyed out if filled contours are selected in the Plan View. Build 11
NCR PDISP-99 Tabular Output Print and Print Preview buttons are incorrectly disabled when the Tabular Output is displayed in the Grid View. Build 8
NCR PDISP-98 Non-linear Curves Use of non-linear curves with zero factors should be prohibited, since this will result in soil with no strength, and so infinite displacements. Build 8
NCR PDISP-97 Toolbars, UI The Line Graph button on the Plan Toolbar cannot be unset when there are results. The user should be able to select or deselect it. Build 8
NCR PDISP-95 UI The file name is missing from the title bar of the Soil Column Displacements View. Build 8
NCR PDISP-93 Help Help file "Label objects" suggests this option is on the "View" menu. It is on the "Graphics" menu. Build 8
NCR PDISP-91 Menus "Soil column displacements" appears on both the "Edit" and the "View" menus when the Tabular Output is active. It should be on the "View" menu only. Build 8
NCR PDISP-89 2D Plan The Plan View is not updated, e.g. to remove contour results, when results are deleted. Build 8
NCR PDISP-83 Miscellaneous Pdisp may crash when opening an existing file from the File menu, when run in a virtual desktop. Build 8
NCR PDISP-79 Analysis Analysis may fail to run with the error message that displacement locations are above soil profiles, though they are equal in level. Despite this fix, when legacy "problem" files are opened in Pdisp 19.3 Build 8 or later, their displacement location, load and soil profile levels may have to be retyped in order to overcome legacy precision issues. Build 8
NCR PDISP-78 Analysis The settlement of points above the level of load may be calculated incorrectly at points in plan when the settlement at level of load is very close to settlement at rigid boundary level. Build 8
NCR PDISP-76 3D Graphics The 3D Graphics fails to display anything if there are no soil zones in the model (though soil profiles). It could usefully assume the first profile to the extent of all other data. Build 8
NCR PDISP-74 Validation Pdisp fails to check correctly that soil strata are ordered by decreasing elevation. Build 8
NCR PDISP-73 Validation, Analysis Pdisp may crash during analysis if the data contains an unreferenced soil profile which has more strata than do the soil profiles that are referenced. Build 8
NCR PDISP-71 Validation Test files that contain polygonal loads should be those not already expanded to multiple rectangles. Build 8
NCR PDISP-70 Validation Pdisp fails to calculate horizontal displacements if soil zones are not specified to cover the whole model (i.e. the extent of all displacement data and loads). This situation should be prevented with an error before analysis. Build 8
NCR PDISP-64 Validation, Analysis A failure in calculation, which produces #1.INF results, will prevent contour plots from being drawn. (The program may appear to hang.) Build 8
NCR PDISP-58 Tabular Output Tabular Output: if Boussinesq results then "Displacement" missing from header which shows "Z" only. Build 8
NCR PDISP-57 Tabular Output, Loads Neither the Loads Table View nor the Tabular Output View shows the units for tolerance for fitting rectangles to polygons if polygonal loads are specified. Build 8
NCR PDISP-50 Tabular Output, Loads The menu command "Window" -> "Position" arranges views with margins outside the viewable area. Build 8
NCR PDISP-49 Help Help File: incomplete description of "Number of Rectangles" in the Load Data page. Build 8
NCR PDISP-48 Help Help Menu: remove "Keyboard Map" which is currenty permanently disabled; reinstate "Tutorials". Build 8
NCR PDISP-47 Gateway The Gateway opens at a fixed, narrrow width, irrespective of the width when the program was last closed. Build 8
NCR PDISP-45 Miscellaneous The Gateway refers to Analysis Options whereas the dialog its selection presents is titled Analysis Parameters. Build 8
NCR PDISP-43 DXF Import Pdisp fails to prompt the user to save a file when closing a file that has had DXF data imported. Build 8
NCR PDISP-42 3D Graphics Pdisp's 3D Graphics may display a reflected image of the model in the plan view, if some or all coordinates are negative. Build 8
NCR PDISP-40 Analysis, Mindlin Pdisp may give zero displacements if the Mindlin method (non-legacy) is selected, and the displacement point is precisely at the level of the junction of two soil layers. Build 8
NCR PDISP-38 Help "Help -> Oasys UserVoice" and "Help->Keyboard Map" are permanently greyed out. Build 8
NCR PDISP-37 Input, Soil Profiles Entering non-numeric text (e.g. "123456789-a") into the Young's Modulus - Bottom cell of the Soil Profiles' table gives a blank error message. Build 8

Item Category Description Status
NCR 9137 Validation Strata should be entered into the soil profiles' table in order of descending level. If they are not then Pdisp should prevent analysis, and warn the user to correct the data. Build 19
NCR 9071 Miscellaneous Checking for errors and warnings on analysis takes longer than necessary. Build 18
NCR 9048 Validation Error and warning messages regarding the relationship in space between displacement locations, loads, and soil zones/profiles should be improved. Build 18
NCR 8630 Analysis Pdisp may calculate zero displacement if displacement points lie precisely at stratum interface levels. Build 17
NCR 8543 Analysis, Validation Displacement data (or load data or soil profiles') levels that are at or below the level of the horizontal rigid boundary level may cause the program to crash upon analysis. Build 17
NCR 8341 Analysis, Displacement Grid Pdisp may hang or crash if a displacement grid is specified with zero width. Build 17
NCR 8321 UI, Displacement Data Repeatedly double-clicking the "Displacement Data" branch on the Gateway opens new table views of displacement data, rather than bringing the view that is already open to the foreground. Build 17
NCR 8008 2D Plan, Displacement Line Pdisp may draw a displacement line in the plan view with its intermediate points' crosses in the wrong places, offset from the line. Build 14
NCR 8004 Export, CSV File->Export->CSV Results offers a check box to "Skip duplicate locations" if they occur. It appears not to work. Duplicate locations (e.g. if start of one line is coincident with the end of a previous line) are output anyway. Build 14
NCR 7996 Validation Soil column displacement graphs are prevented for displacement points that clearly lie in soil zones and so should be allowed. The check on a point's location may incorrectly report that the point lies outside all soil zones. Build 14
NCR 7995 Analysis Pdisp allows calculation of displacements for points outside soil zones (see NCR 7974) on "analysis" but does not allow it in soil column displacements. Build 14
NCR 7985 Validation Pdisp needlessly informs the user that there are no data check warnings before performing an analysis. It should simply continue with the analysis. Build 14
NCR 7981 Menus The Soil Column Displacements menu option is missing from the program menu when the Tabular Output is active. Build 14
NCR 7979 Displacement Line If a displacment line with coincident start and end coordinates is analysed, then Pdisp gives an "Out of Memory" warning, and Youngs Modulus units are subsequently corrupted e.g. by a conversion factor such as 1000. Build 14
NCR 7975 Imported Displacements Pdisp fails to include imported displacements in the Soil Column Displacements graph. Build 14
NCR 7974 Analysis, Validation Pdisp incorrectly allows calculations of displacements for locations (displacement data or load centres) which are above the top levels of their corresponding soil profiles. Build 14
NCR 7940 Analysis Pdisp calculates displacements for points lying outside soil zones, without warning the user and clarifying which soil profiles are assumed. Build 14
NCR 7855 Soil Column Displacements Soil Column Displacements graphs may be prevented for valid coordinates - the program incorrectly stating the coordinates have no soil profile. Build 14
NCR 7904 Imported Displacements Pdisp may fail to combine imported displacement results in some instances when it should do for coincident points - though it correctly indicates in the Tabular Output those which have and have not been combined. Build 13
NCR 7850 Validation If a ".pdt" or ".vdt" file, containing a list of other pdisp files for testing, is selected for batch testing, then the files listed must be in the folder from which the program is running, rather than wherever the ".pdt" or ".vdt" file is. Build 13
NCR 7610 2D Plan Line contours in the 2D Plan View may be incorrectly labelled with the label of the neighbouring contour. Build 12
NCR 7393 3D Graphics, Validation Pdisp may give the warning "Enter a number" when visiting or leaving the "Displacements" page of the 3D Graphics Wizard. Build 11
NCR 7343 2D Plan The 2D Plan View may fail to colour the lowest contour when filled contours are chosen. Build 10
NCR 7337 Soil Column Displacements The error message "Encountered an improper argument" appears, and a blank window opens, if the Soil Column Displacements graph is opened for a model whose soil zones do not cover the coordinate x = 0m, y = 0m. Build 10
NCR 7327 2D Plan Line contours in the plan view may be stepped along grid lines, rather than continuous. Build 9
NCR 7263 Graphs, Displacement Lines Displacement lines' displacements' graphs are stepped as though they only plot distances to the nearest integer distance e.g. the nearest 1m. Build 9
NCR 7184 Graphical Input, Displacement Data Pdisp crashes when entering displacement grids, lines or points in the 2D graphical input view, if no displacement grids, lines or points have previously been entered. Build 8
NCR 7098 Imported Displacements When importing displacements from Pdisp into Xdisp the imported displacements may have rounded, or otherwise very slightly different coordinates sufficient to prohibit a match when combining results. Build 7
NCR 7097 Imported Displacements, Tabular Output Imported displacements are not shown in the Tabular Output with sufficient resolution. Build 7
NCR 7063 Export Exporting displacement results from Pdisp into Xdisp may fail to generate matches, though identical displacement coordinates are intended, due to inaccurate precision of coordinates. Build 7
NCR 7038 Tabular Output Tabular Output is not updated automatically when the number format in the Preferences Dialog is updated. Build 7
NCR 7037 Tabular Output Tabular Output fails to show displacement data to sufficient detail for them to be distinguishable. Build 7
NCR 7017 Displacement Data Copying displacement data from Xdisp's to Pdisp's displacement data tables causes loss of resolution so intended identical points no longer match in the two programs. Build 7
NCR 6975 3D Graphics The 3D Graphics View may fail to open, leaving the program hanging. Build 7
NCR 6956 Results Displacements may be reported as "-1.#IND0". Build 7
NCR 6918 Input Pdisp's PSIC input view displays only one set of curve data as the tabs are clicked to change the curve being displayed. Build 7
NCR 6917 UI When opening the PSIC table from the gateway by double-clicking the last PSIC entry in that branch, the program crashes. Build 7
NCR 6914 3D Graphics Pdisp may fail to plot displacement contours correctly in the 3D Graphics View. Build 7
NCR 6827 UI, Displacement Data, Tabular Output Pdisp's indexing of displacement grids, lines and points differs (by 1) depending on whether viewing data in the input Table View or the Tabular Output. Build 7
NCR 6702 2D Plan Pdisp may fail to plot line contours on the 2D Plan View for a displacement grid whose second point's x value is less than the first point's x value, or whose first point's y value is less than the second point's y value. Build 6
NCR 6235 Tabular Output Pdisp's Tabular Output should indicate the units of vertical strain: absolute or %. Build 5
NCR 6408 3D Graphics Display of deflected displacement points and lines cannot be turned off in the 3D Graphics View. Build 4
NCR 6371 Menus The program menu's "Graphics" menu allows graphical input of displacements and loads, but not soil zones. Build 4
NCR 6366 2D Plan Soil zones can be toggled, but not labelled in the 2D Plan View. Build 4
NCR 6365 2D Plan The Plan View does not allow components to be labelled, although labels for grids, lines, points and loads are offered in the program's menu. Build 4
NCR 6363 Graphical Input The Graphical Input Plan View shows all components in black. They should be coloured for easy distinction. Build 4
NCR 6334 Graphics The cross section plot fails to show the strata with filled colours. Build 4
NCR 6331 3D Graphics If results are available, and displacement points are selected to be shown and labelled in both deflected and undeflected positions, the 3D Graphics View labels both positions as "...(Deflected)". Build 4
NCR 6329 3D Graphics Displacement points cannot be "turned off" in the 3D Graphics View, even though the Settings Wizard is set not to display them. Build 4
NCR 6323 2D Plan Pdisp's 2D Plan View does not allow toggling on and off of displacement points, lines and grids. Build 4
NCR 6321 2D Plan After selecting a bitmap as the background for the plan view, the error message "bitmap not created" may, at some point, be output, and the bitmap no longer shown. Build 4
NCR 6320 2D Plan The bitmap chosen in the background of the plan view is not persistant on closing and re-opening the view, or closing and re-opening the data file. Build 4
NCR 6277 Graphs, Displacement Lines Pdisp may fail to display line graphs of displacements for displacement lines correctly. Build 3
NCR 6245 Reading Pdisp reads soil zones incorrectly, removing characters from the start of the name field each time the data file is opened (after saving), until there are no characters and the program warns that soil zones cannot be read. Build 2
NCR 6244 Reading Pdisp gives a default value of 5kN/m2 for load in the tangential y direction. A default of 0kN/m2 would be more sensible. Build 2
NCR 6216 2D Plan Pdisp fails to display contour plots for displacement grids in the 2D Plan View correctly. Build 1
NCR 6186 Non-linear Curves, Input Data is not preserved correctly in the non-linear curves table. Entering data and then clicking "Add Curve", or closing the view, causes the data to be lost. Build 1
NCR 5579 Displacement Data, Input The "Show Detailed Results" toggle in the Displacements Table View is only effective for Displacement Grids. Build 1
NCR 5314 Input, Soil Profiles Double-clicking a soil profile in the gateway opens the soil profiles table but with the first soil profile's tab active, not the soil profile that was selected. Build 1
NCR 5313 Non-linear Curves Deleting the sole remaining non-linear curve leaves a rogue curve with no data. Build 1
