Include geometric nonlinearity comsol

WebJan 4, 2024 · December 14, 2024 COMSOL Employee Hi Abdullah I guess you want to include geometric nonlinearity. We can do this, but you might want to add some more objectives/constraints for topology optimization to make the problem more well-posed. Shape optimization might be a better fit in this case. WebThe Structural Mechanics Module enables you to model large deformation with geometric nonlinearity and follower loads. Loads can be distributed and may also depend on other physics, such as electromagnetic or fluid flow forces. Mechanical contact is of course available and is multiphysics enabled.
