Can I modify the Jacobian for an analysis?

Please login with a confirmed email address before reporting spam

I would like to use a user defined constitutive model with the structural module. The constitutive model calculates the stress tensor and the jacobian. How can I modify the entries of the Jacobian in Comsol?

Thanks for your replies.
