Hello,
A segmentation error occurs when it is in the Optistruct section trying to starting analysis my model, the screenshot of the proplem attached, how can I fix it ?
In general, segmentation errors can be solved by deleting settings files, see https://community.altair.com/community?id=community_question&sys_id=044688761b2bd0908017dc61ec4bcb69
In cases of backward incompatibility, a good workaround is to export the files as a solver deck for example, and import it in previous versions.

In this case of segmentation error, verify the name you have given to this job, their should not be any space or dash in between, if there replace it with underscore"_"
