It was written to work in 3D, not sure about 2D.
Do you have a 3D test?

Add this solver after calc fields. It will compute time-dependent core loss. Add core loss properties in solver: Solver ... Equation = "MGDynamicsCalc" Procedure = "MagnetoDynamics" "MagnetoDynamicsCalcFields" Linear System Symmetric = True Potential Variable = String &...

The GSE approach works for sinusoidal excitations. Plus it can account for non-linear magnetic properties.
Let me know if you want to try it out.

Hi,

Assuming that this is transient simulation, do you think the Generalized Steinmetz Equation would work?

Hi, This is not a commercial post of mine, but I would like to suggest you to try TRAFOLO https://trafolo.eu/download-page/ It generates Elmer's sif files and runs it so you can get some ideas out of it. Free for non-commercial use. We would be very happy if you could do comparisons with other solut...

Hi, I get an error related to MPI on Windows 10. MPI version is one that comes with Elmer. The case has ~1M elements, memory >20GB. When running the case in serial without MPI, it works. Is this buffer size hardcoded (e.g., CheckBuffer @ SParIterComm.F90) or there is a way to increase it? SolveLinea...

Hi! I am trying to export Joule Heating e (elemental field) from one simulation and import it into another simulation. The export/import happens on the same mesh, but different sif files. Export Simulation has Output File = data.restart Output Global Variables = Logical True Import Simulation has Re...

Hello, Is there a way to nullify/clear an old WhitneyAVHarmonicSolver solution (Bicgstabl) during the Scan simulation type? I am using the B-H curve model and running a Scan with different frequencies. It seems that every next scan, the solver uses the solution from the previous scan. This seems to ...

Hello Eelis,

You are right about removing "body" namespaces. Once removed, it works. Thank you!

"circuits_harmonic_foil_anl_rotm" case produces non-circular currents.

Hello, This is three coil case with foil windings. Two sif files: 1) Alpha and Beta boundary conditions are grouped - this case works. 2) Alpha and Beta boundary conditions are separate - this case does not converge. Do you have ideas why this might happen? This works (converges): ... Boundary Condi...
