Re: Toy hierarchical problem
You use many of the default constants on Elmer and Elmer materials these are in SI units therefore the physical dimensions are to be in meters. Your geometry looked very large so I threw in a scale factor of 0.001, but I do not know if that is correct. Having the wrong dimensions could cause diverge...

Re: Error using CoilSolver
In the manual page 171 there is a solver flag
Desired Coil Current
https://www.nic.funet.fi/pub/sci/physic ... Manual.pdf
So you could take off the body force and use Desired Coil Current
See test case

Re: FreeCad FEM mesh: boundary, region and group. Which one and when?
In 3d groups of solid elements become bodies, groups of plate elements become boundary surfaces. 1D elements are eliminated if you use -autoclean. ElmerGUI uses -autoclean by default.
In 2D models groups of plate elements become bodies, groups of 1D elements become boundaries.

Re: Understanding mechanical simulations with boundary contacts
This was my attempt, with and without the magnets. Without the magnets and no need for contact, the rotor deforms as expected.
with magnets on the left, without on the right
on the left it appears to deflect inward instead of outward as expected. The white is undeformed

Re: Toy hierarchical problem
Sphere for the air is better, 1 infinity boundary, and the BC is written for the spherical case.

Re: Toy hierarchical problem
These are the names of the bodies and boundaries in your mesh ! ----- names for bodies ----- $ body = 1 $ enclosure = 2 ! ----- names for boundaries ----- $ inlet = 1 $ outlet = 2 $ walls = 3 $ left_face = 4 $ front_face = 5 $ right_face = 6 $ back_face = 7 $ top_face = 8 $ bottom_face = 9 So the BC...

Re: Coupled Fluid-Structure Eigen Analysis
There is a contributed case index on the board, your case would make a great contribution.

Re: Computing E field in Vacuum Capacitor
The vacuum or air should completely surround the plates so as to have an infinity BC on the outer surface. I prefer a sphere because the outer surface better matches the BC.
