Hi !
I would like to simulate a 3D Gaussian Beam Laser Pulse. In Comsol version 3.5a it works well, but in version 4.2 there are the error messages:

"Failed to find consistent initial values.
Internal error in solver.
Last time step is not converged."

I would very much appreciate any hints to adjust the model from 3.5a to 4.2 as well as difference between this two versions seems to me enormous.

Thanks a lot

Robert
