Hi:
I am solving the following problem (solvability condition satisfied)
"a(u,v)- lam* b(u,v) = L(v),
where lam (non-zero) is the eigenvalue and the non-trivial null space is spanned by gfu, i.e. a(gfu,v) = lam* b(gfu,v)."
I assume that one cannot simply assemble the bilinear form "a(u,v)- lam* b(u,v) ", since lam is an eigenvalue. Is there a way to solve this PDE in netgen?
Any help is greatly appreciated.
Best,
