Hypermesh issues with picking and more.

dave_m

I have a linear static model that worked fine in nastran. After conversion to optistruct the hypermesh interface no longer picks/filters correctly or works once or twice before resetting (via exit restart) to work one or two more times.
Additional issues — while solving the optistruct .fem file it stopped on element quality checks on QUADs that were almost perfectly square — these were also connected to grounded CBUSH elms. Deleting the QUADS allowed the model to run.
Deleting the Command.tcl file doesn't affect change anything.
Running HM 2024.

Hi Dave,

Optistruct always checks element quality when you submit any analysis run.

Did you get any warning/error related to mesh quality. If you feel your model has godd mesh quality and you want to skip the quality check, then use PARAM,CHECKEL,NO card.

Try running with this and see if the run goes through.

Thanks
