What's New

What's new in Version 5.9.1

Release notes

•This is a cumulative update – all previous versions may be skipped when upgrading.

New Features

•Added option in Settings to toggle visibility and set color of major and minor grid lines on all graphs.

Enhancements

•Improved handling of post-buckling analysis. If string lockup occurs, earlier versions displayed an error message and aborted the calculation. Now the calculation is performed to a point where string tension (compression) is greater than the available string weight above that point (i.e. surface tension = 0). All calculations are completed and a warning is displayed for each operational model where lockup occurs.

Bug fixes

•Input now also validated before executing the calculation. In case of invalid input (e.g. no survey data or string elements), calculation is aborted and all input warnings are displayed.

•Added check to Drillstring; if Tool ID > Tool OD, calculation is aborted and a warning is displayed.

•Correction in Settings. If checkbox for 'Make current setting my defaults' was left unchecked, settings were incorrectly saved. This caused settings in the file to be ignored and all settings to revert to the default when opening a file.

•Small correction in Stiff String calculation.

•Corrected small bug in graph scaling (zoom, unzoom and pan). If zooming was reset, 'Manual Scaling' in Settings was not reset.
