alternative shape optimization algorithm

Reza Karshenas

hello everyone,

Does anyone have any idea what exactly an alternative shape optimization algorithm is in Optistruct? I've searched in the help, but haven't found a concrete explanation. 

thanks

Xiaolei

Hey Reza,

Can you have a look at free-shape optimization?

Hello Xiaolei,

thank you for your reply. Yes, I know the general idea of shape optimization you sent me. I was searching for the important factors that have a great influence on free shape optimization and I came across "DOPTPRM, SHAPEOPT" which defines an optional parameter to select an alternative shape optimization algorithm but I don't know exactly these alternative shape optimization algorithm. 

Thanks for your help and tips.

Sincerely yours.
