Re: Salome wrong body in Elmer

This is the tutorial I used. It works.

Re: volume iso-contours paraview

You might be able to use the "threshold" filter to select a volume region of interest, then use the "integrate" filter to integrate the volume (the volume/area should be one of the values computed I think).

whitney3d current density in non-conducting region

Hello, as the title says, I am wondering why the current density as computed by the field solver is non-zero outside of conductors. Current density should, of course, be (electric field vector)x(electric conductivity). I always thought it was because of the "Fix Current Density" option tha...

Re: Magnetic field with eddy currents 2d/3d

I've seen that sort of thing before and I think it was because I wasn't writing the vector fields to file correctly. For one thing, I should think that your current density will be a complex quantity. So I would think you would want to write the imaginary and real parts of the current density to fil...

Re: Compilation on HPC

You'll want to look at both of these: http://www.csc.fi/english/pages/elmer/sources http://www.elmerfem.org/elmerwiki/index.php/Compiling_Elmer_parallel_version_%28Linux%29 I recommend you make a folder in your home directory called maybe 'bin'. You can set to install to ~/bin/elmer using the prefix...

Re: Magnetic field with eddy currents 2d/3d

I looked briefly at the team7 thing. I think whitneyav solver will not like splitting a driven coil up into pieces because at the cut edges you have div(j)->infinity, and for the solver you need div(j)=0 everywhere (which also means you can't account for capacitive effects). If splitting it up into ...

Using cylindrical symmetry with whitneyAV

I think this is not possible but I thought I should ask if there is any trick to get around the problems: I want to take (for simplicity of the problem description), a cylindrical solenoid at the origin, surrounded by a spherical "vacuum/air" body that is large, and compute the magnetic fi...

Re: Magnetic field with eddy currents 2d/3d

Here is a test case I made for 3D time domain eddy currents. It is a conducting ring surrounding a solenoid with linearly increasing current. I think you should be able to adapt it to frequency domain pretty easily as a next step. You will, of course, need to convert the gmsh2 format mesh "sole...

Re: Import .geo or .msh file

Mesh it in gmsh -> cone.msh

Then from the command line

ElmerGrid 14 2 cone.msh -autoclean

Type 'ElmerGrid' from the command line to see a explaination of what the numbers mean and different options of ElmerGrid.

Re: Compilation error of parallel fem

if mpif.h isn't in /usr/lib64/mpi/gcc/openmpi/include, then that is your problem.
