Dear Community,
I have a problem when creating an Optistruct model for freesize optimization including a ply drop-off (PLYDRP) constraint.
In particular, I created such a model in Hypermesh 2017 with different design variables (DSIZE). If I export the model in Optistruct format (.fem) and I import it again in Hypermesh 2017, I am not anymore able to see all the DSIZEs but I can see only one of it.
I have created a simple model to give you an example.
In the file attached, you will find (among the others) four DSIZEs: top, bottom, left, and right. The PLYDRP constraint is activate for all of these design variables.
If I export the model to an Optistruct input file (.fem) and I import it again in Hypermesh, I cannot see anymore the four DSIZEs, but only one of them (top) is still there.
This happens only if PLYDRP is activated.
I would really appreciate if anybody could give me an explanation about this strange behaviour and what to do to avoid it.
Thank you in advance,
Alessandro
