Greta 18.2 Build 1: New Features

Calculation of ultimate bearing capacity of soil and bearing, sliding and overturning checks have been implemented.
A tool for finding the most optimised base width of the wall to achieve full mobilization of soil strength has been implemented.
A 'Gateway' window has been implemented to provide easy access to input data, tabular data and graphical views.
The Greta Toolbar has been implemented to provide easy access to the most frequently used views and commands.
The menu structure has been re-arranged to provide a separate 'Graphics' menu to access settings for the Graphical Output view.
Periodic web activation for Arup and Unipac editions added. (Release 4 onwards.)

Factor of safety taken input only as integers. i.e. factor of 1.5 is treating as 1.
[NCR 1832] (Fixed 09 August 2007)(Released 13 August 2007 in Release 2)
Vertical soil weight on back of wall incorrect
[NCR 2351] (Fixed 24 December 2007)(Released 24 December 2007 in Release 3)
Fixed the error in calculation of Pore water pressure which is leading a low bearing capacity values
[NCR 2374] (Fixed 24 December 2007)(Released 24 December 2007 in Release 3)

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.

[NCR 20] (Fixed 26 April 2006)
Help files seem to be not connected properly to the Help menu button in the application.
[NCR 23] (Fixed 10 April 2006)
The Groundwater pressures entered were not being used in the calculation and not even showed in graphical view; only the hydrostatic pressures were being used in the calculations.
[NCR 24] (Fixed 21 March 2006)
Ground water data is assumed to be entered in ascending order of levels which is not being done so, and that too in SI units only and not in any other units.
[NCR 25] (Fixed 21 March 2006)
The units in the results output seem to be in consistent with the values for the force units being invariably in the KN range even though other units may be requested by the user.
[NCR 26] (Fixed 5 May 2006)
