How to apply a constant current

Please login with a confirmed email address before reporting spam

I want to model a transformer winding in 2D in different frequencies and calculate the resistances. I need to apply a constant value of current to these conductor, which have equal amount of current, but I do not know how to do it. Please help me in this case.

Hi

If ou had V4.1, I would say:
for me you sould start to read carefully the doc on the multi-turn coil BC's, then try them (bulk metal, single/multiple turn coils) out to with different BC's, and get a good understanding of how they work, then I believe you should be able t solve your model successfully
in 3,5 you do not have these nice new BC's (boundary Conditions) so you need to write out fully the equations.

There were a few threads about a year or more ago discussing multi turn coils in COMSOL 3.5

Good luck
