Yield and Ultimate Strength
Hello, How can I add Yield and Ultimate strength? My material is isotropic so ı will use Mat1 but I didn't find yield strength section.

If you're looking to add a non-linear material to your model you can use the MATS1 option on the MAT1 card. In order to include that material in a non-linear subcase you'll need to add a NLPARM card to the subcase.
Thank you, but My material is Inconel 718 and linear. I want to add those properties for topology optimization and safety factor.
Altair EmployeeI see, in that case you don't need to change anything with the material property itself. You can just add a design constraint to the topology optimization problem. You can add stress constraints by property or element sets using a DRESP1 static stress response. Or you can add a global stress response on the topology design variable.
Here is a tutorial for the global topology stress constraint:

You should look into attending one of the Optistruct for Optimization classes, we cover this in detail.

How can I attend the classes ?
