How do I generate .sh file (for OSSMOOTH) from the results of a topology optimization study?

Altair Forum User

Hello,

 

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!

 

Thanks

Hi @Branden Little

 

Did you try to change the ISo value on OSSmooth?

 

By changing the threshold (iso) value on OSSmooth, the topology changes. Please try this and let us know if this helps.
