Customize the physics equations

Please login with a confirmed email address before reporting spam

Hello everyone,

I am modeling a set of experiments in which I need to make some changes to the default equations and relatively new to COMSOL.

In the CFD module, what I would like to to do is to make one of the parameters a function of two-phase flow interface curvature.

Second, in the Structural Mechanics module, I would like to add an extra stress term to one of the either linear of nonlinear viscoelastic models. The extra stress can be a constant (which I think is easy) or a function of surface curvature.

I appreciate your helps.

Best,
