Pdisp 19.2 : Fixes

  • Deleting the sole remaining non-linear curve leaves a rogue curve with no data.
    [NCR 5313]
  • 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.
    [NCR 5314]

    [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.

  • 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)".

  • The cross section plot fails to show the strata with filled colours.
    [NCR 6334] (Fixed 13 September 2011) (Released in Build 4)
  • The Graphical Input Plan View shows all components in black. They should be coloured for easy distinction.
    [NCR 6363] (Fixed 21 September 2011) (Released in Build 4)

    [NCR 6235] (Fixed 4 November 2011) (Released in Build 5)
  • 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.
    [NCR 6702] (Fixed 26 January 2012) (Released in Build 6)

Geo 18.1 Build 5: New Features

  • Data files may now be emailed directly from the program's interface via the 'File' menu.
  • The text output of the results view has been improved. It may now be exported to a range of file formats via the 'File' menu.
  • Standard sets of units (SI, kN-m, kip-ft and kip-in) may be selected via the Units and Preferences dialog.
  • So as to help users to ensure that they are running the latest software a new version checking system has been implemented. This compares each executable file installed locally with the set that Oasys identifies as being the 'current' version. (The comparison is carried out locally; no data is transmitted to Oasys.) Executables for which updates are available are highlighted. Updates may then be downloaded from the Program's Downloads page on the Internet. This system enables rapid delivery of bug fixes and, occasionally, minor enhancements.

Geo 18.1 Build 5: Fixes

  • Saving of condensed results only doesn't appear to be correct. When the data file is saved only the results for the first point on the grid are stored, it should store the results for all of the grid points, and the first element of the level array within each grid point.

  • Contouring intervals - some omitted at end of range - gap in filled contours.
    [NCR 12] (Fixed 16 June 2005)

    [NCR 20] (Fixed 26 September 2005)
  • "Displacements at area centroids" option allows only at level 0.
    [NCR 21] (Fixed 18 October 2005)
  • Unnecessary soil profiles that contain no strata data should be ignored, rather than creating 'empty' soil profiles.
    [NCR 22] (Fixed 18 October 2005)
  • Vdisp may crash during an analysis.
    [NCR 42](Fixed 30 June 2006; released in VddCal.dll 30.0.1.0)

Outstanding Bugs

  • Giving all entities a �Name� field would help to interpret results in the output view, rather than having to rely on the numerical IDs only.
    [NCR 2382]
  • When outputting coordinates in the OS coordinate system, their resolution is lost to the output view by truncation to fit the column widths.
    [NCR 2383]
  • Pdisp fails to update the user on progress of calculations, giving the impression, during large calculations, that the program has hung.
    [NCR3828]
  • Load vectors are not shown correctly.
    [NCR 4180]
