My problem is below:
I'm using Coefficient PDE mode. There are two PDEs and the dependent variables are A and B, seperately. Now I defined a variable C in global variable and C=A^2+B^2. When I compute the model, the error returns as Undefined variable A so Comsol failed to evaluate variable C.

How do I solve this problem? Thanks all.
