Hi,
I'm having two functions say u1 und u2 and two test functions v1 and v2. At the moment I'm using the "Vector Lagrange" Functions to declare u and v as a vector.

I would like to solve my PDE with u1 and v1 defined on mesh1 (approx. 2000 nodes) and u2 and v2 defined on a different mesh2 (approx. 20 nodes). I would like to get a 2020x2020 matrix. Both meshes will be contain exectly the same area.
Is there a change to declare the bilinearform in such a manner?
