Hello everyone,
I am currently working on a simulation in COMSOL Multiphysics involving two partial differential equations (PDEs) with three dependent variables T, V, and P.
Specifically, I have the following conditions:
When T > 5, I assume V = 0. In this case, the system can be simplified to include only equations for T and P.
When T < 5, I assume P = 0. In this case, the system can be simplified to include only equations for T and V.
What I would like to ask is how to define the dependent variables of these two PDEs: T, V, and P, because within my ability two PDEs can only define two independent variables, and the third one I can't add.
Thank you!
