I modified the test case to use coordinates x, y, and z.
No mag function in MATC, may consider writing a user function.

I changed the air mesh to a cylinder, not sure that matters. If I plot coilcurrent, which is supposed to nodal values it is 15000. If I plot coilcurrent e , which is supposed to be elemental values it is 30000.

Taking this case of steady state stress due to heat

and then modifying it to read a time history from a file and do transient.

I took a cylinder of the same size and meshed it in a sphere of air and a cylinder of air and the results were very different. Same element type and density.

You can search this forum for PCB, there have been PCB models discussed.

With your geometry it my be best to stick with a cylinder for the air with a mesh similar to Figure 14.1 on page 91

The air volume in paraview can be turned off and one by using the threshold filter, filter on geometry IDs, you can filter to only show the bodies you want to see. In the run I posted I had put voltage on the outer skin, and ground on the inner skin. I will re-run with voltage on the end. I tried me...
