    [NCR 4415](Fixed 11 August 2010; released in Xdisp 19.2 Build 9)
  • Though "Mair et al" is chosen as a sub-surface analysis method, the analysis warnings and Output View may suggest the soil type has been set to "granular" incorrectly. However, the results are unaffected.
    [NCR 4819](Fixed 12 August 2010; released in Xdisp 19.2 Build 9)
  • Changes made to an excavation's Surface Level and Contribution are not reflected if the coordinates' table is modified.

    [NCR 5443](Fixed 25 November 2010; released in Xdisp 19.2 Build 10)
  • Xdisp may fail to read Polygonal Excavations correctly from saved Xdisp data files - when those excavations were originally created by import from a DXF file, and when the polyline that describes the excavation has coincident start and end points. This may subsequently cause the program to crash when opening the Polygonal Excavations input view.
    [NCR 6154](Fixed 23 June 2011; released in Xdisp 19.2 Build 12)
  • The Input Data Wizard is not accessible from the Buildings Table View. When attempting access the program warns "Attempted an unsupported operation."
    [NCR 5071](Fixed 28 May 2010; released in Xdisp 19.2 Build 13)

  • File | Export | Building Damage Assessment Data... crashes Xdisp when run on Windows 7.
    [NCR 6261](Fixed 5 August 2011; released in Xdisp 19.2 Build 14)
  • The manual describes Boscardin's k derivation formula incorrectly as "i = 0.5 z0 + 0.25 metres" and "i = 0.24z0 + 0.5 metres" for cohesive and granular soils respectively, rather than "i = 0.5z0" and "i = 0.25z0".

    [NCR 6367](Fixed 19 Sep 2011; released in Xdisp 19.2 Build 17)
  • The help manual should be more explicit that the source of the O'Reilly and New formula of i = 0.28z - 0.12 for granular soils is Figure 4 of O'Reilly and New's paper as opposed to the text, which shows a less precise Equation 13 of i = 0.28z - 0.1.
    [NCR 6485](Fixed 10 Nov 2011; released in Xdisp 19.2 Build 18)
  • The default values for excavation corner stiffening parameters p1* and p2* would more sensibly be 67 and 25 respectively, rather than 100 and 50.

  • The Mair et al method should calculate zero soil movement for displacement points below the invert of a tunnel.
    [NCR 6495](Fixed 5 Dec 2011; released in Xdisp 19.2 Build 18)
  • If the New and Bowers method is chosen for sub-surface ground movements, then only "User-defined k" should be offered as the k derivation method and not O'Reilly and New or Boscardin.
    [NCR 6497](Fixed 6 Dec 2011; released in Xdisp 19.2 Build 18)
  • Xdisp may crash when a building's displacement graph is queried if the displacements are all less than the sensitivity limit.

  • Import of displacement results from CSV
  • "One click" export of building damage assessment results' tables and graphs
  • Extension of building damage interaction chart to compressive strains
  • Implementation of Harris and Alvarado tunnel method
  • Taylor adjustments to Mair et al tunnel method

[ top ]

Xdisp 19.1: Minor Enhancements

  • If two or more imported displacement lines start at the same point, Xdisp would only import the displacement at that point for the first line. Xdisp now: (1) collects all the imported displacements from the file and at the time of analysis checks for coincident points; (2) assumes results are entered in the import data file with tag POINT_RESULT instead of entering grid, line and point results with separate tags (GPOINT_RESULT, LPOINT_RESULT, POINT_RESULT); (3) sums all imported displacements with the value calculated by Xdisp, when there are multiple entries of displacements at a point in the import file; and (4) adds imported displacements to the values calculated by Xdisp for all the points in the model with coincident co-ordinates (irrespective of type of data i.e grid, line or point.)
    [ME4481](Added 15 Feb 2010; released in Xdisp 19.1 Build 13)
  • Added horizontal displacements resolved along the building line to the export of building damage assessment data.
    [ME4495](Added 15 Feb 2010; released in Xdisp 19.1 Build 13)
  • Warning given if sub-structure crosses an excavation since building damage results in that portion should be treated with caution.
    [ME4499](Added 16 Feb 2010; released in Xdisp 19.1 Build 13)
  • Displacement lines report, in the Tabular Output: "Displacement Parallel to Line"; "Displacement Perpendicular to Line"; and "Angle of Line to Global Axis".
    [ME4500](Added 16 Feb 2010; released in Xdisp 19.1 Build 13)
  • Xdisp modified to use the displaced horizontal distances when calculating points of inflexion and therefore segment lengths for building damage calculations. The program previously used un-strained horizontal distances when determining points of inflexion. The tabular output reports segment lengths according to their pre-strained situations. This change will be insignificant in the vast majority of cases.
    [ME4501](Added 16 Feb 2010; released in Xdisp 19.1 Build 13)

Xdisp 19.1: Fixes

  • Xdisp may fail to import displacement data correctly. Displacement data whose coordinates should match those in the data file may be omitted.
    [NCR 4383](Fixed 18 Dec 2009; released in Xdisp 19.1 Build 10)
  • Unnecessarily double-spaced lines of data appear in the Tabular Output's table of "Building Damage Results - Critical Values for All Segments within Each Sub-Structure".
    [NCR 4401](Fixed 5 Jan 2010; released in Xdisp 19.1 Build 11)
  • Upon clicking a coordinate in the Displacement Data table view the coordinate displays itself to more decimal places than have been entered by the user.
    [NCR 4402](Fixed 5 Jan 2010; released in Xdisp 19.1 Build 11)
  • Exported Building Damage Results may be misleading if horizontal strain for a sub-structure's segment is in compression. Maximum combined tensile strains (total bending, total diagonal and max.) do not consider the compressive horizontal strain value.
    [NCR 4403](Fixed 6 Jan 2010; released in Xdisp 19.1 Build 11)
  • The Tunnels Table View will not allow "granular" soil to be set. On setting it and closing the view, the soil reverts to "cohesive".
    [NCR 4450](Fixed 2 Feb 2010; released in Xdisp 19.1 Build 13)
  • If the O'Reilly and New sub-surface k deriviation method is chosen, then Xdisp incorrectly sets i using the user-specified k value, irrespective of whether the user-defined option has been set. It should use that k value if user-defined is set, but should otherwise derive k from the i value according the O'Reilly and New derivation formula.
    [NCR 4452](Fixed 2 Feb 2010; released in Xdisp 19.1 Build 13)
  • Xdisp may incorrectly calculate and report displacements within excavations where those displacements arise from tunnelling, but correctly does not allow them from excavations.

    [NCR 4485](Fixed 18 Mar 2010; released in Xdisp 19.1 Build 14)
  • The program may crash while performing analysis including building damage assessment.
    [NCR 4648](Fixed 15 Apr 2010; released in Xdisp 19.1 Build 15)
  • Displacement point coordinates are converted to scientific if their values are too long for their column in the Tabular Output. Grids which are made up of points whose values are large, but differ by small increments, may be listed with indistinguishable point values.
    [NCR 4649](Fixed 15 Apr 2010; released in Xdisp 19.1 Build 15)
  • Xdisp may give the warning 'encountered invalid argument' and crash, when the Tabular Output is opened when line results are not listed as the first displacement data items, i.e. before grids and points.
    [NCR 4656](Fixed 16 Apr 2010; released in Xdisp 19.1 Build 15)
  • Exporting displacement contours to CSV may fail unexpectedly (though the contours can be viewed in the Plan or 3D Graphics View) with the warning "The specified contour interval is inappropriate for Grid n and X/Y/Z/Resultant Direction. Contours will not be output for that combination.".
    [NCR 4658](Fixed 20 Apr 2010; released in Xdisp 19.1 Build 15)

    [NCR 3906](Fixed 10 September 2009; released in Xdisp 19.0 Build 12)
  • Displacements may fall to zero at distances from a tunnel where significant displacements are anticipated (e.g. the displacement line graph has a slope discontinuity at the penultimate point before zero displacement is reached).
    [NCR 3996](Fixed 17 September 2009; released in Xdisp 19.0 Build 12)
  • Xdisp may give incorrect results when using the New and Bowers method.
    [NCR 4005](Fixed 28 September 2009; released in Xdisp 19.0 Build 12)
  • A second displacement data table may be opened when one is already displayed. This is confusing. Instead, an attempt to open a second table e.g. from the Gateway should activate the already-displayed table.

  • Tunnel labels are not visible on the plan view, despite clicking the "label" toolbar button.
    [NCR 3872](Fixed 24 September 2009; released in Xdisp 19.0 Build 12)
  • The "Apply" button on the 3D Graphics Settings property sheet does not work. Settings must be applied by clicking "OK".

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.
  • The Mining application type has been implemented as a beta feature.
