I am a student user from Canada, working on a topology optimization project for my university's Formula SAE Team.
I have completed my optimization study using OptiStruct, and have manipulated the iso result in HyperView to something that I am somewhat satisfied with. I now wish to use OSSMOOTH to smooth out my model and convert it to a .STEP file so that I can open it in SolidWorks as a solid body. OSSMOOTH requires you to load a .fem file and a .sh file. I know that when you run the topology optimization study, it automatically generates a .sh file for the final iteration (and an arbitrary iso-clipped value), but the automatically generated .sh file does not contain the iso-clipped geometry that I wish to move forward with.
My question is this:
How do I import my desired iso-clipped geometry into OSSMOOTH? Am I required to generate a new .sh file from my desired iso-clipped geometry? If so, how do I create this file? I can't seem to figure out how to get my desired shape to appear in OSSMOOTH, so perhaps there is a gap in my knowledge about file types and how to create them. Any help/advice would be greatly appreciated!
