Electrical Circuit and Comsoll

Dear memebers I Work with Comsol 4.3 ACDC. I know now how to import a SPICE Netlist to Comsol.But I still have a problem. I followed the exmaple in ACDC modul called "inductor in a Circuit". So to be...

Re: Electrical Circuit and Comsoll

Hi Ahmed, yes, that's the problem. I now believe, that It is not possible to place the source for the FD-Analysis into the circuit. The usual way to do a FD-Analysis in Comsol is to build two Terminals...
