How can I simulate a two-coil problem in ANSYS Maxwell 13?

AI Thread Summary
To simulate a two-coil problem in ANSYS Maxwell 13, users face challenges compared to FEMM, particularly in defining frequency and obtaining matrix outputs. The setup involves two coaxial copper coils with specific turns and currents, where the user seeks to replicate inductance results from FEMM. While transient mode was attempted, it lacks a direct method for defining frequency and does not provide the desired output parameters. Users are interested in whether it's possible to input the number of turns directly in Maxwell and how to calculate induced voltage. Clarifications on these functionalities would enhance the simulation process in Maxwell.

Hi everybody,

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 ?

I just realized that multiplying the inductance given in Maxwell 13 by N2 the result is the desired inductance... Is it possible to obtain the result directly ? I mean, isn't it possible to enter number of turns in Maxwell ? This is a simple axisymetric problem.

Also, how can I get induced voltage in Maxwell 13 ?
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
