  [NCR1241](Fixed 7 March 2007; released in Release 1)
• Geotextile pull-out calculations incorrectly ignore 'reinforcement pull-out factor' and 'economic ramifications of failure factor'. The help manual incorrectly suggests that Shear Strength of Soil τ = (σ_μ'tanδ + c_a)/(f_p/f_n) whereas is should be .../(f_p x f_n).
  [NCR 1507](Fixed 22 May 2007; released in Release 2)

  not prompted to delete existing results when the deleting property sheets.
  [NCR 1957](Fixed 10 September 2007; released in Release 3)
• Deleting property sheets that are in use by certain strata, is not prevented. In addition, the references of the data items such as
  groundawater tables, piezometric data etc. are not updated.
  [NCR 1960](Fixed 10 September 2007; released in Release 3)
• Groundwater tables are plotted in the graphical output even if they are not active for any stratum.
  Also, hatching should be removed for these GW tables. Need to check whether same thing applies to piezo sets.
  [NCR 1964](Fixed 10 September 2007; released in Release 3)
• Slope may warn that layers overlap when they are specified to have coincident surfaces.
  [NCR 2192](Fixed 23 November 2007; released in Release 4)
• Font size button not working in tabular output.

• Slope 18.2 fails to read fully a file written with version 17.7. It gives a warning regarding the 'slips' module.
  [NCR 2321](Fixed 7 December 2007; released in Release 4)
• The default value for effective width of geotextile would more usefully be set to 100% rather than 0%.
  [NCR 2328](Fixed 11 February 2008; released in Release 5)
• The default value for whether reinforcement is active or not would more usefully be set to "active" rather than "inactive".
  [NCR 2329](Fixed 11 February 2008; released in Release 5)
• The reinforcement property sheet's "Apply" button is not enabled when the bond length selection is changed.
  [NCR 2390](Fixed 7 January 2008; released in Release 5)
• Slope crashes if "Do not keep history of recently opened documents" Group Policy is set, and "File | Open" is selected.
  [NCR 2498](Fixed 7 February 2008; released in Release 5)
• Slope may incorrectly report "Common point too close to stratum point".
  [NCR 2508](Fixed 8 February 2008; released in Release 5)
• The help manual fails to give the meanings of f_cr, f_m11, f_m12, f_m21, f_m22 and f_n.
  [NCR 2511](Fixed 12 February 2008; released in Release 5)
• Contouring may produce misleading results if the 'save/display rejected circles' flag is unset in the Slip Definition data.
  [NCR 2721](Fixed 12 May 2008; released in Release 7: additional fix for files saved with earlier versions made on 12 June 2008)

  [NCR 2626](Fixed 7 Nov 2008; released in build 12 (Slope.exe 18.2.1.10))
• Partial factor on adhesion incorrectly applied to specified bond strength of soil nails.
  [NCR 3209](Fixed 7 Nov 2008; released in build 12 (Slope.exe 18.2.1.10))

Geo 18.1 Build 5: New Features

• Data files may now be emailed directly from the programs' interfaces 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.
• Stratum specific ground water has been implemented. The user can now input phreatic surface and piezometric data specific to each stratum. A number of changes have been made to the user interface in order to facilitate this feature e.g. data entry of Strata, Groundwater and Piezometers. Graphical input has been improved to facilitate entry of multiple phreatic surfaces and piezometric profiles.
• Ability to enter and analyse multiple non-circular slips in one data file added.

• Prestress in anchors applied per anchor, not per m run.
  [NCR 25] (Fixed 19 May 2006)

Outstanding Bugs

• When an "Open" dialogue box is opened, it would be good if (a) there was a "favourites" button, using the user's favourites as in Explorer, and (b) data/time appeared naturally without reorganising the box.Could the box be bigger?The box should re-appear each time with the format previously adopted by the user. [O-140].
  [NCR 2]
• Horizontal extension of strata and showing on the graphical output may not be correct.
  [NCR 7]
• Program extends problem limits in the graphical output beyond those defined in the input data - but extends the strata horizontally, this may not be correct.
  [NCR 16]
• Horizontal extension of strata and showing on the graphical output may not be correct.
  [NCR 33]
• Problem with "Full" message, if entering new data and activate reinforcement but without setting a valid set of partial factors. Problem does not occur if reinforcement inactive.
  [NCR 40]
• The program crashes if items on the Groundwater table's context menu are exercised.
  [NCR2450](Fixed 28 January 2008)
