Hello,

I'm currently working on topological optimization using the optistruct solver, but sometimes I have to import a file (.nas) on hypermesh that already contains the optimization job, the problem is that the moment I import the file (.nas) in hypermesh it has many errors that appears
and when I validate and I chose to export the file with optistruct, I find that the file export does not contain the optimization cards the question what do I have to do for these optimization cards to appear in the export file?

Best.

    Hi @elmejjati

     

    Not all cards are converted to OptiStruct supported cards from Nastran,

     

    You may have to recreate the optimization cards in OptiStruct.
