Could you upload your sif file?
Maybe your mesh too if it is not too big?

Hello,

Is there any way to select the shape functions in elmer?
If I try the same mesh in Elmer and Comsol I need a much finer mesh in Elmer to get the same results.

Edit: I am using the WhitneySolvers and the MagnetoDynamics2D

I do not really know the exact answer but If it solves your problem I wouldn't worry about it.

I think there aren't any but compiling (at least with gentoo) is really straight forward.

The numerical solution searches the (local) minimum so you give a threshold to stop. The convergence monitor shows you the state of your solution progress. In this graph you can see how fast your solver converge. I would suggest you to use paraview for post processing. Just change your sif file to P...

Hello,

In the models manual there is the body force My problem is I need real and imaginary part of current density.
Is there any way to give both parts?

Edit:
I have the same problem with the MagnetodDynamics2DHarmonic solver.

I think you need the coefficents of the cubic spline function.
In your case file there are german words so I think you can handle this site:

I hope this will help.

If you need fast a 2d only simulation maybe give femm a try. It is much easier to understand but elmer is much more powerful. But i found another thing you should look at. From the elmer models manual: B-H Curve Cubic Real The B-H curve must be given as a cubic spline. This enables that the derivati...

I think the SaveLine Solver is the right for me. In the 2d case I can use Solver 3 Exec Solver = After Simulation Equation = SaveLine Procedure = "SaveData" "SaveLine" Filename = "line.dat" Polyline coordinates(2,2) = -5e-3 5e-4 -5e-3 4.45e-3 End But I didn't get it to ...

I tried your code on win7 and Linux. On Win7 I got some errors like ERROR:: Model Input: For property name:[target variable complex] . On Linux there was a convergence problem. After changing the bh to relative permeability 1 it worked on Linux. So I think you have at least two problems. Your Window...
