Re: EM_levitation

Hi again, As I (Roland) can no more access my own account since a few days(Again Peter, can you do something so that I can recover my account?) I use the Elmer_forum account of my colleague Laurent... At first thank you very much for your latest efforts, Kevin and Peter! As you say, Peter, concernin...

Re: Whitney solver - Wire test case total current calculation

PROBLEM RESOLVED: Hi Peter, I uploaded the latest build of Elmer and my .sif file now returns the correct values for the total current! Many thanks for your help! really appreciated. Here is a brief summary of the solution so that the Elmer community can beneficiate from this experience Solver 2 Equ...

Re: Whitney solver - Wire test case total current calculation

Hi Peter,
fab! that is really good news.
Can you please share your .sif file as I'm still struggling and failed to get to your results.

look forward to seeing your .sif file.
Thanks

Re: Whitney solver - Wire test case total current calculation

Hi Peter, I confirm the values returned by SaveScalars for the total current have some errors The true values for the total current are: Re=0.16 and Im=-2.95 whereas Elmer returns Re=0.0465 and Im=-2.86 note: potential applied to the wire is 0.01V at a frequency of 160kHz the Imaginary part of the t...

Re: Whitney solver - Wire test case total current calculation

Many thanks Peter, some good progress here as Elmer now exports the total current 1: boundary int: current density re 3 over bc 3 2: boundary int: current density im 3 over bc 3 3: res: eddy current power 4: res: electromagnetic field energy I got this result with the following commands Variable 1 =...

Re: Whitney solver - Wire test case total current calculation

Thanks for your prompt reply Peter

I tried your suggestion and the solver returns an error:

ERROR:: SaveScalars: For convective flux of a scalar we need the convective field!

Re: Whitney solver - Wire test case total current calculation

Hi Peter, One way of tackling this would be to run the surface integral of the current densities over the model boundary. I tried SaveScalars by adding a solver to the .sif file Solver 5 Equation = "SaveScalars" Exec Solver = After All Procedure = "SaveData" "SaveScalars&quo...

Whitney solver - Wire test case total current calculation

Hello everyone, With regards to the 'wire' test case sitting at https://github.com/ElmerCSC/elmerfem/tree/devel/fem/tests/mgdyn_harmonic_wire, can someone please advise on how to get Elmer to compute the following values: * the total current across the wire * the resistance of the wire * the inducta...
