Hello,
I'm starting to work with optistruct and would like to include the optimization of the stiffness modulus (E modulus) in my model. Running an optimization where the material orientation of a composite structure is specified as a design variable (DESVAR) is straight forward, but is it also possible to specify a design variable for the E1 and E2 values when trying to maximize the normal modes of a structure?
kind regards,
Mark
Please use DESVAR and DVMREL1/2 cards to define the material property as the design variables. DVMREL1/2 are not available in HyperMesh GUI. So you need to manually add/edit the card in your .fem file. You can find more information by searching DVMREL1 or DVMREL2 in online help.
