Hi,
I'm using the sol 200 MSC Nastran to do a sturctural optimization.
My model is made up of PSHELL and PBARL elements and the goal is to minimize the weight of the structure.
To do this I've utilized the DRESP1 WEIGHT for all the structural weight,as a objective function, but since in my model...
Hi,
I'm using MSC Nastran to do a structural optimization with sol 200.
My model is made up of PSHELL(CTRIA3 and CQUAD4) andPBARL(CBAR) elements.
I've defined von mises stress responses by DRESP1 entry and I've linked them to the DCONSTR enty becouse I don't want elements overrides 233 MPa...
Hi,
I'm using the sol 200 for a structural optimization but I have problem with the stress responses.
I've used four type of DRESP1:
1) DRESP1 198 S198 STRESS PSHELL 9 198
2)DRESP1 1198 S198 STRESS PSHELL 17 198
3)DRESP1...
Hi,
I've done a structural optimization with sol 200 of Nastran.
In my model I've imposed stress constraints using the DRESP1 and DCONSTR cards.
So, I've runned the model first whit Nastran NX and after with MSC Nastran.
The two f06 are different, I imagine becouse they utilizes different...
