How to solve PDE in comsol

Please login with a confirmed email address before reporting spam

Hi comsol support team

                                     I am mani Shankar yadav research intern from IIT Ropar India. I am facing problem while solving PDE solution in comsol. 

be expressed by the following continuity equation: ∂nD/∂t= ∇⋅(D∇nD- vnD+DSnD∇T )

Here, nD is the n suffix D.

In this equation how to introduce third term (DSnD∇T) at right hand side in order to solve PDE equation.

Hi, Gupta

From the figure you attached, are you solving a whole system of 5 coupled PDEs?

And are you asking about how to implement the 3rd term of the equation you mentioned?

Could you provide more details on your question? Besides, e.g., which COMSOL modules are you using?
