Hi,
I am trying to couple joules heating with laminar flow in 3D geometry using COMSOL 4.1 (64 bit win XP OS). However I am getting the following error while solving:

Failed to find a solution.
Out of memory during LU factorization.
Returned solution has not converged.

Does the solver setting need to changed? I shall be highly obliged if anyone can kindly help.

Thanks and regards,
Debashis

I must do some calculations with the results of an eigenvalue PDE. E.g. add two eigenvectors (in 2D) to each other or get the "exp" of the eigenvalues. Although I can see and select different eigenvalues, but I don't know, how to ask COMSOL to give me second or third ... eigenvalue or eigenvectors for some post processing.
Is there any simple way to put label to each of eigenvalues or eigenvectors?
