defining integral in comsol

Please login with a confirmed email address before reporting spam

Hello,

I'm new to Comsol.
I'm using the electrostatics module to solve for the potential and electric field.
Then I want to define a variable P which is an integral of a function dependent on the electric field.
P is used to solve another PDE.
The bottom line is that I have a few coupled equations.
How can I define this integral (P)?

Thanks in advance
Tom

Have you tried using a component coupling? (Component > Definitions > Component Couplings >Integration )
See Reference Manual, version 5.2, page 281 and following for detailed information on Component Couplings.
Best,
Jeff
