Hi everyone, I am doing a project for the subject of aerodynamics and I am using AcuConsole for that. I am finding some problems with the CATIA reader I have installed with AcuConsole, so I am thinking now switching the file format to stl (seems more reliable). The problem I am finding now is that I cannot split the model into different surfaces, to assign the airfoil, the sides, etc. I tried to divide the geometry with the feature angle, changing it from 90 degrees to 0.1 and doesn't allow me to pick up any geometry when I create a new surface group. Could you help me to solve that problem? I attached the files if anyone wants to try. Thank you beforehand. Guillermo Flow Domain.stl
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 plydrop_issue.hm
