I am new to Maxwell, simulating a planar transformer. I imported the PCB from Altium and am doing eddy current analysis. The primary (blue) and secondary (red) are excited through the large vias in dark blue and red. I have created an air box which is trimmed such that the faces of the vias to be excited are touching the edge. There should be two conduction paths going through primary and secondary coils, with both paths being driven by multiple parallel current excitations on all the large vias. When I validate, I get the error shown at the bottom of the screenshot saying that the conduction paths cannot be found. I have never done this before and want to know if I can manually define the conduction paths, or if importing from Altium is causing a problem. Thanks<\/p>\n
