hi all, i need some help about modeling a coil on maxwell 3D(transient analysys.).my problem is defining coil terminals.i have 6 coils(star connected) and 3 current source(star connected).i attached my work.coils are solenoid style winded.(ring style winding) and each coil has 130 turn.i design my model,i upload external circuit netlist to maxwell then i got this error when i validate my design..(by the way i try to do my analysys on transient solution type.) "[error] Verify conduction path 'Path2': For any conduction path that has coil terminal excitation(s) specified, either exactly one internal coil terminal or two external coil terminals should be specified." i have google it but i got nothing... any turtorial/manual or lecture notes??or any idea how to define coil terminals? sorry for my bad english.
