Hi Ivar,
Thank you for your suggestion! I was reading this as you must have been replying:
For time-dependent problems, the time-stepping algorithm must know if a problem is complex valued. If your model uses a complex-valued initial solution, COMSOL Multiphysics detects this and classifies the problem accordingly. If the problem is complex-valued because of a complex-valued PDE coefficient or other material property, go to the Solver Parameters dialog box, find the General page, and select the Allow complex numbers check box.
This solution works perfectly - I wish I had read this yesterday lunch time ;-)
Regards,
Tom
