Important Bug Notification

This is to notify you of two important bug fixes for SPACE GASS 14.50.155 — one that prevents axial forces in compression truss elements from being displayed correctly, and one that prevents Von Mises stress max and plastic strain contours being displayed correctly.

1

Truss elements in compression displaying zero force

Details of the bug

When truss elements are in compression, the force in the truss element was still zero, or near zero, and therefore the displayed results for those elements is incorrectly shown as zero, or near zero. This affects the displayed and reported axial forces for compression truss elements only. Truss elements in tension are not affected.

Affected versions

Version 14.50.155 only, released on 27 July 2026. No earlier versions were affected.

Remedy

Fixed in version 14.50.159

The problem is fixed in version 14.50.159 and all later versions, released from 12 August 2026 onwards. If you have one of the affected versions then we strongly advise you to upgrade to the latest version.

2

Non-linear materials — Von Mises stress max and plastic strain contours displaying incorrect values

Details of the bug

When a non-linear analysis with non-linear materials is run for multiple load cases, the contour results were unintentionally accumulating between load case runs, resulting in incorrect values being displayed. This affects the Von Mises stress max and plastic strain contours only. All other contour types are unaffected and display correct values.

Affected versions

Version 14.50.155 only, released on 27 July 2026. No earlier versions were affected.

Remedy

Fixed in version 14.50.159

The problem is fixed in version 14.50.159 and all later versions, released from 12 August 2026 onwards. If you have one of the affected versions then we strongly advise you to upgrade to the latest version.

Other fixes

A number of other minor bugs have also been fixed in later versions of 14.50, so it is recommended that you upgrade even if you have v14.50.155 or newer.
