- Revision to digital signature of installer.
[ME PDISP-67](Fixed 17 May 2016; released in Pdisp 19.3 Build 6)
- Inclined displacement lines are not shown in the Plan View, so their line graphs of results cannot be selected and shown.
[ME PDISP-41] (Implemented 12 November 2016; released in Build 8)
- Import Xdisp data file (but displacement data only to Xdisp version 19.3).
[ME PDISP-44] (Implemented 2 February 2016; released in Build 8)
- The Analysis Options FormView may open with some content/buttons accessible only by scrolling.
[ME PDISP-51] (Implemented 4 March 2016; released in Build 8)

[ME PDISP-52] (Implemented 17 February 2016; released in Build 8)
- The title of the Tabular Output wizard (“Page Setup”) is misleading. Change to e.g. “Tabular Output Selection”.
[ME PDISP-53] (Implemented 17 February 2016; released in Build 8)
- 3D Graphics: Removal of titles and warning re comparison of Mindlin v Boussinesq (moved to Analysis Dialog and Tabular Output).
[ME PDISP-54] (Implemented 19 February 2016; released in Build 8)
- Do not present page set up dialog after analysing (and set all check boxes to true by default when it is opened).
[ME PDISP-55] (Implemented 19 February 2016; released in Build 8)
- Move Wizard column to start of polygon loads columns.
[ME PDISP-56] (Implemented 22 February 2016; released in Build 8)

[ME PDISP-59] (Implemented 7 March 2016; released in Build 8)
- The 3D Graphics Settings Wizard (Displacements’ page) is unusable when large numbers of imported displacements are available.
[ME PDISP-61] (Implemented 8 April 2016; released in Build 8)
- Writing 19.2 files (for GSA use) from 19.3.
[ME PDISP-62] (Implemented 19 July 2016; released in Build 8)
- Import of Xdisp files (insofar as is possible i.e. displacement data, background data, restuls and imported results).
[ME PDISP-69] (Implemented 13 June 2016; released in Build 8)
- The 3D Graphics Settings should more helpfully default to a wire frame view since load and displacement data is then visible.
[ME PDISP-72] (Implemented 5 July 2016; released in Build 8)
- Improved (less obtrusive) data validation in table views. Some validation delayed to pre-analysis check.
[ME PDISP-75] (Implemented 29 July 2016; released in Build 8)

[ME PDISP-86] (Implemented 4 November 2016; released in Build 8)
- Error message re rigid boundary level would better point the user at the Analysis Options dialog for resolution.
[ME PDISP-87] (Implemented 7 November 2016; released in Build 8)
- Filled contours can only be activated in the Plan View when line contours are already selected. This is an unnecessary restriction.
[ME PDISP-88] (Implemented 7 November 2016; released in Build 8)
- 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.)
[ME PDISP-90] (Implemented 8 November 2016; released in Build 8)
- Removal of warning in Displacement Data table re >99 intervals to prevent possible repetitive warning. Moved to pre-analysis checks.
[ME PDISP-92] (Implemented 8 November 2016; released in Build 8)
- 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.
[ME PDISP-94] (Implemented 12 November 2016; released in Build 8)
- 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.)
[ME PDISP-112] (Implemented 13 January 2017; released in Build 11)
- The alignment of warnings in the Tabular Output is poor. It would also benefit from numbering there and in the Analysis Dialog.
[ME PDISP-118] (Implemented 3 February 2017; released in Build 13)
- Update to licensing.
[ME PDISP-130] (Released in Build 16)
- Pdisp’s Analysis Parameters checkbox “GSA raft analysis data” might better be named “GSA piled raft data”.

- Unnecessary warning message while data input in Soil Profiles table.
[NCR 9359] (Fixed 11 November 2014) (Released in Build 1)

[NCR 3828] (Fixed 12 November 2014) (Released in Build 1)
- Tooltips for the toolbar items of plan are not working.
[NCR 9455] (Fixed 11 December 2014) (Released in Build 1)
- Vertical loading plane is shown horizontal in the graphical input.
[NCR 9451] (Fixed 12 November 2014) (Released in Build 1)
- A 3D Graphics View of an undeflected displacement grid is filled whether the “Filled Polygon” check box is checked or not. If not, then it would be expected to show an empty “net” of grid lines with no fill. The fill hides other items in the display.
[NCR 8342] (Fixed 02 September 2014) (Released in Build 1)
- There are no options in the preferences dialog to enable/disable undo-redo feature and set the number of undo-redo steps.

[NCR PDISP-64] (Fixed 16 November 2016; released in Build 8)
- 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.
[NCR PDISP-70] (Fixed 7 November 2016; released in Build 8)
- Test files that contain polygonal loads should be those not already expanded to multiple rectangles.

- 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.
[NCR PDISP-79] (Fixed 13 September 2016; released in Build 8)
- Pdisp may crash when opening an existing file from the File menu, when run in a virtual desktop.
[NCR PDISP-83] (Fixed 22 September 2016; released in Build 8)

[NCR PDISP-89] (Fixed 7 November 2016; released in Build 8)
- “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.
[NCR PDISP-91] (Fixed 8 November 2016; released in Build 8)
- Help file “Label objects” suggests this option is on the “View” menu. It is on the “Graphics” menu.

- If horizontal displacements/loads are specified, and the model contains overlapping soil zones or gaps in soil zones, then Pdisp may calculate incorrect results.
[NCR PDISP-111] (Fixed 10 January 2017; released in Build 11)
- Analysis options are not all reported in the Tabular Output.
[NCR PDISP-113] (Fixed 13 January 2017; released in Build 11)

- Switching from “Condensed” to “Full” in the Tabular Output has no effect.
[NCR PDISP-115] (Fixed 18 January 2017; released in Build 11)
- Licensing fix (commercial builds only).
[NCR PDISP-120] (Fixed 31 January 2017; released in Build 12)

[NCR PDISP-121] (Fixed 6 February 2017; released in Build 13)
- The Tabular Output is not updated after making changes in its wizard.
[NCR PDISP-122] (Fixed 14 February 2017; released in Build 13)
- 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.
[NCR PDISP-123] (Fixed 8 February 2017; released in Build 13)
- Pdisp crashes if an analysis is attempted with a polygonal load which has no polygon coordinates.
[NCR PDISP-126] (Fixed 11 February 2017; released in Build 13)

- The “Show Detailed Results” toggle in the Displacements Table View is only effective for Displacement Grids.
- 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.
- Pdisp fails to display contour plots for displacement grids in the 2D Plan View correctly.
[NCR 6216] (Fixed 21 July 2011) (Released in Build 1)
- Pdisp gives a default value of 5kN/m2 for load in the tangential y direction. A default of 0kN/m2 would be more sensible.
[NCR 6244] (Fixed 1 August 2011) (Released in Build 2)
- 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.
[NCR 6245] (Fixed 1 August 2011) (Released in Build 2)
- Pdisp may fail to display line graphs of displacements for displacement lines correctly.
[NCR 6277] (Fixed 23 August 2011) (Released in Build 3)

[NCR 6329] (Fixed 13 September 2011) (Released in Build 4)
- 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)”.
[NCR 6331] (Fixed 13 September 2011) (Released in Build 4)
- The cross section plot fails to show the strata with filled colours.
[NCR 6334] (Fixed 13 September 2011) (Released in Build 4)
