Glad you figured it out. I was trying to recreate your case by using gmsh to mesh it. However, I had convergance issues. One thing I noticed was that, your frequency was really high, 1 MHz. You had fine mesh on the surfaces but was it fine enough for Elmer to give you good results? I don't know. I w...

I had the same issue. when I downloaded 5.12 and used it. It went away. there is a bug with 5.10. some libraries changed recently apparently.

Hi, I am doing a similar thing with the harmonic solver. The first thing I noticed is that you don't have Permeability and Permittivity defined in your materials. Here are the material data I used. Note that it's in yaml format. Also for the boundary setup, here are my setup and I think they are wor...

I think I understand it better now—thank you for the prompt reply. In my case, since I have a closed coil, I need to make a cut in the coil to apply the boundary conditions (BCs) and avoid using the coil. To accurately calculate the eddy effects, I should not use the CoilSolver. Is this assumption c...

Hello, I am currently working with two simulations: one using "Electric Current Density" and the other with CoilSolver. Both simulations are intended to achieve similar results. However, I've noticed that the simulation with CoilSolver does not accurately show the eddy effects. Could you c...

I was able to figure this out.

This is due to the fact that the current is being applied to surface, evenly. This is expected.

Here is what I found that seems to be working. Header CHECK KEYWORDS "Warn" Mesh DB "." "." End Simulation Max Output Level = 6 Coordinate System = Cartesian Coordinate Mapping(3) = 1 2 3 Simulation Type = Steady state Steady State Max Iterations = 1 Output Intervals(1)...

Hello everyone, I greatly appreciate the power and utility of this tool. I'm currently engaged with Tutorial 7, which explores the magnetic field induced by a harmonic current in a wire, using ElmerGUI. I've transitioned to working directly with the SIF file. My current challenge involves altering t...
