Creating the design and non design spaces

Hello all,

 

I am new to topology optimization and I need your help to create the design and non-design spaces.

What is the best way to do this?

 

Should I create 2 different bodies in the part in Catia V5 in order to get 2 different components in Hypermesh, and then connect and mesh them?

In this case, how could I connect the 2 components?

Or should I create only one main body and define the non design space within Hypermesh? (But the design of the part is not simple. I fear this might be difficult)

 

Feel free to contact me if I'm not clear enough

 

Thank you very much

 

Best regards

Florian
