Brinkman equation

Please login with a confirmed email address before reporting spam

Hi,

I am trying to implement Brinkman's equation in COMSOL.

I don't have microfluidics module of CFD module.

So, I want to apply the following differential equation in the general from PDE.

My geomerty is a square box. (in 2D axial symmetry domain) There was some difficulty in writing down the equation into the COMSOL, but I think I manage to write down the correct equation. I put no flux, pressure, and velocity boundary conditions. However, COMSOL cannot find the solution for my PDE. I am not so sure why COMSOL is having diffculty in solving my system. May someone give help?

Thanks,

Yang.
