Re: Whitney Solver Parallel: Performance and Memory Organisation

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

Shape functions

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

Re: Mesh model question

I do not really know the exact answer but

Code: Select all

Volume elements: 0
If it solves your problem I wouldn't worry about it.

Re: Where are the Linux Binaries for ElmerGUI?

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

Re: Convergence History

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...

WhitneyHarmonicAVSolver complex current density

Hello,

In the models manual there is the body force

Code: Select all

Current Density Im i Real
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.

Re: B-H Curve MagnetoDynamics2D

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.

Re: B-H Curve MagnetoDynamics2D

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...

Re: Export solution in specific area

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 ...

Re: B-H Curve MagnetoDynamics2D

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...
