I've replicated the first tutorial of FEMM (https://www.femm.info/wiki/MagneticsTutorial) using Elmer.
The worflow is as follows:
FreeCAD Design and Mesh -> Elmer definitions -> Paraview post processing
At this moment, I can integrate variables using Paraview, but I can't get the same result as FEMM when I use Axis Symmetric. For planar (cartesian) the result matches.
To compare the results, I'm integrating over surface the magnetic potential.
I'm not sure if Paraview understand that the result is (r, rho,z) or if I must pre-treat it somehow.
I've tried
Code: Select all
Coordinate Transformation = String "cartesian to cylindrical"
FEMM result with A integral.
Elmer definitions (sif attached)
The result using paraview
For a general information: A = Potential
FEMM = 1.28184e-11
Elmer -> Paraview = 9.99684e-11
Any suggestions?
PS: I can't attach my mesh since it is bigger than 1Mb.
