Coefficient form pde in comsol

Please login with a confirmed email address before reporting spam

Hi

I want to solve these three pdes in comsol. I am using the coefficient form in comsol.

How do I type the first equation in comsol?

∂n/∂t=D∇^2 n-∇.(σ/(1+c).n∇c)-∇.(ρn∇f)

The equation has two ∇ terms.

I have attached the equations in a word file

Please help

Thank you
