Free-shape optimization in Radioss

Hello,

 

first of all i'll present what i need to do, i need to develop impact absorbing composite structure from scratch. I have a next algorithm in mind for doing this:

 

  • Radioss free shape optimization - start geometry is a square profile, objective: minimum volume inside the shape, constrains: buckling, stress, displacement.
  • Radioss free size optimization - after obtaining a geometry composite optimization for thickness, objective: minimal weight, constrains: failure of specific elements, buckling, displacement, acceleration.

 

And now questions:

 

  • Is there a way to make free size optimization in Radioss?
  • Is it possible to share step by step guides for any Radioss optimization?

 

Thanks in advance.

    Hi,

     

    There are tutorials available on OptiStruct helps. Please go through the tutorials
