Eigenvalue included in boundary condtions

Dear all,

I wish to input lambda into my subdomain and boundary conditions, whilst using the PDE coefficient form.

Does comsol v4.0a allow this feature.

Kind Regard

DE

Hi

what do you really mean by using/entering lambda into your model ?

That one I do not understand, I would need a little more explanations there to be ale to perhaps have an answer ;)

I suspect he wants to use lambda, which is the in-built variable name for the eigenvalue, in the boundary conditions for an eigenvalue problem. For instance, for the flux/source boundary condition, is it possible to use lambda for q?
