Dear community,
I am trying to implement the following problem Laplacian eigenvalue problem:
\int Grad(<f,u>) dA = \lambda \int u*f dA with Dirichlet boundary conditions and a Neumann condition.
Since this problem is observed on a mesh with n Triangles The equation is to be solved on every triangle and the corresponding fem.
Is my idea of using the following _expression_ for the lhs correct?
getfem::mesh mymesh;
I am really unsure about how to implement this problem. Do you have an idea? Or should I use the "bricks"? Although I am not sure either if this would work..
How can I make sure that the problem is for real implemented on each trinagle of the mesh?
