Important Bug Notification

This is to notify you of an important bug fix for SPACE GASS 14.50.155 to 14.50.161 — that affects the results of jobs analysed using the SG-X solver.

1

Results of jobs analysed using the SG-X solver

Details of the bug

When jobs are analysed with the SG-X solver. For members that run in a negative global axis direction, intermediate member results in reports and steel member design may in some cases be calculated with an incorrect local axis orientation. Results shown graphically on the screen, member end results, and jobs analysed with the standard solver are not affected. The issue has been corrected, and we recommend reanalysing any affected jobs after updating.

The same problem also affected dynamic analysis. If the dynamic frequency analysis was run with the SG-X solver, a subsequent spectral response analysis could produce incorrect results for those members as well.

NOTE: Other solvers (Paradise and Wavefront) were not affected

Affected versions

Version 14.50.155 released on 27 July 2026, to version 14.50.161 released on 17 Aug 2026. No earlier versions were affected.

Remedy

Fixed in version 14.50.164

The problem is fixed in version 14.50.164 and all later versions, released from 21 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 v14.50.161 or newer.
