Hi everybody,(adsbygoogle = window.adsbygoogle || []).push({});

I would like to compare inductance (self and mutual) calculations using FEMM and Maxwell 13, both 2D problems. In FEMM this is very simple and I just use an axissimetric solution, enter the desired frequency, currents and get the results.

When using Maxwell, however, this seems to be much more complicated. Please I appreciate your help on simulating this problem:

Two coaxial copper coils, frequency 15 kHz. Coil 1 has 16 turns, radius 56.5 mm and I represent the winding as a 1 mm radius circle in Maxwell, current i1 = 28 A. Coil 2 has 12 turns, radius 73.98 mm and I represent the winding as a 1 mm radius circle in Maxwell, current i2 = 0 A (open circuit). Distance between coils is 42.9 mm.

Currents are sinusoidal.

FEMM results are: L1 = 78 uH and L2 = 66 uH.

I tried to use Maxwell in transient mode (but could not find where to define frequency). Moreover, transient solution does no provide "Matrix" as output parameter...

Please, how can I simulate this geometry with Maxwell ?
