Relaxation and penalization factor

sagar_20757

Hi,

 

I was going through some research papers, where q-p relaxation method was mentioned for topology optimization.

Where q- Relaxation parameter and P - penalization parameter.

So, I would like to know, how to co-relate these q & P parameters with the parameter being used in optistruct for topology optimization.

 

Thanks

OptiStruct solves topological optimization problems using the density method, also known as the SIMP method (Solid Isotropic Material with Penalization) in the research community. Refer attached document for topology optimization and below link for optimization algorithm.

Hi,

Thank you! this is really helpful.

 

can you please clarify the one more below point.

In many papers, aggregation and block aggregation methods were mentioned. Is it possible to simulate these methods using optistruct?

 

Thanks
