Hello,

 

I am a member of a Formula Student Team from Metz, France and I'm new to Optistruct and to the optimization of laminates. I'm working to optimize our carbon steering wheel. The analysis was done but i have an error when i'm trying to optimize.

I have two optimization response ( mass and static displacement), my optimization constraint is a displacement of 1mm of two nodes and my objective is the min mass. I share my model.

 

My error is  :

 *** ERROR # 2148 ***

 

 Invalid design problem.

 

 All the sensitivities of response   1 (objective) are zero.

 

 

 

Any ideas about a possible reason for this error?

 

Many Thanks,

 

Olivier Hagmann

    This is not the same thing because, for the Desvar, my type is STACK and not PSHELL.

    Hi Olivier Hagmann,

     

    Can you try volume response instead of Mass?
