Include an auxiliary differential equation in a Comsol Multiphysics model via a PDE mode

Please login with a confirmed email address before reporting spam

Hello everybody,

As said in the title, I need to add an auxiliary differential equation to incorporate second-order or third-order nonlinear effects in the RF/photonics module of Comsol Multiphysics. I have already found the property DPE, but I don't know the steps to add it in the software.

Could anyone help me?

Thank you!
