I have a question regarding to create my own PDE in COMSOL, I know that I have to use one of three templates available in COMSOL but still I don’t know how to transfer my high nonlinear equation into one of the equation templates.

Could anyone please help

]]>Yes, of course you do need to know the boundary conditions, but once you figure that out, you certainly can solve two coupled Poisson equations in COMSOL. ]]>

As a matter of fact, I have two Poisson equations with two different source term ( D^2 =f1 and D^2=f2 , D^2 is Laplacian) in 2D and , I do not know what is the boundary condition. Would it possible to use the equation based modeling in Comsol to solve this kind of equations?

Best Regards
