Calculate magnetic torque

Hi everyone! I have some Problem with the calculation of magnetic torque. I found 2 possibilities in Elmer: 1. as a component: Component 1 Name = string "metal" Master Bodies(1) = integer 4 Torque Origin(3) = Real 100 0 -100 Torque Axis(3) = Real 0 0 100 Calculate Magnetic Force = Logical ...

Re: Relative permeability ignored?

The picture of the slice looks like there is a small different between the side with steel and the opposite side without it. Paraview have the option "Probe Location". With this function you can check if the relative permeability is 1000 or 1 (or something else). And maybe you should use t...

Re: Interpolation Method for H-B Curve

Hi Peter, I tried it and it's excactly what i needed! Thx :) Code example: Solver 6 Name = "SaveDep" Procedure = "SaveData" "SaveDependence" Filename = dep.dat Lower Limit = Real 0.0 Upper Limit = Real 1.5 Number of Points = Integer 100 Expression 1 = Variable "dum...

calculate displacement with maxwell stress (mgdyn)

Hi! How is it possible to get the displacement caused by the magnetic forces? I have the maxwell stress tensor and the nodal forces. First problem: But I don't really know which element of the stress tensor in elmer (numbered from 1-6) belongs to which element in T_x,x ; T_x,y ... Second: it is poss...

Re: Interpolation Method for H-B Curve

Another question: is it possible to print that interpolated curves in Elmer or in the postprocessor? (paraview would be nice)

Interpolation Method for H-B Curve

Hi Elmer-users, Did anyone know how the H-B curve for a nonlinear electromagnetic steel is interpolated during the calculation? I use the the method which is described in: https://github.com/ElmerCSC/elmerfem/blob/devel/fem/tests/mgdyn_bh/case.sif H-B Curve(31,2) = Real INCLUDE HB Thank you in advan...

Re: BC for infinite longe wire

I got it on my own. In fact pretty easy. Only have to set AV {e} 2 = 0 and AV {e} 1 = 0 for all BCs in z-direction

BC for infinite longe wire

Hi, At the moment I try to create some simple cases for myself to get into Elmer electromagnetic simulation. At the moment I have a problem with the boundary condition for an infinite long wire. My model consists of 4 cylinders/hollow cylinders. In the middle the wire, than air, electrical steel (at...

Re: Magnetodynamics Solver, wrong magnetic field strength?

Some additional information:

wire:
r=5mm
l=100mm

core:
r=10mm
R=100mm
l=100mm

boundary:
r=120mm
l=120mm

The assigned boundary is only the lateral area of the outer cylinder.
If someone want the project files, I will upload them.
