Re: ElmerGrid weirdness
They are boundary elements so if you do not target those boundaries in the sif file and impose boundary conditions on them they will be ignored by the solver. Same with bodies, if you do not create the body in the sif, a body in the mesh will be ignored.

Re: electrodynamic forces on busbars
This project couples magnetic force to displacement, although the magnetic field is not electrical induced
but you should be able to go from electrical field to magnetic field to mechanical force

Re: Random crashes while repeatedly running the same script
After the refining by splitting, I recombined the triangles to quads, went 2nd order, and the all of the errors went away and a solution was obtained.

Re: Random crashes while repeatedly running the same script
I would suspect mesh quality. I downloaded the files and ran as is and I received the numerous ERROR:: ElementMetric: Degenerate errors I did a refine by split 1 time in gmsh and that error went away I then received a non-convergence error ERROR:: ComputeChange: Numerical Error: Norm of solution app...

Re: SaveScalars solver in parallel
If your mesh is in the current directory and your number of cores specified for the solver is the same as the number of partitions then
Mesh DB "." "."
should be ok since your mesh is in the current directory.

Re: Coupled Fluid-Structure Eigen Analysis
I went to the test cases
HelmholtStructure
HelmholtStructure2
HelmholtStructure3
and change the density from 1 to 1000, and the sound speed from 300 to 1443.
In each one there was no difference in the structural result, but the pressure calculation changed.

Re: Toy hierarchical problem
and that is going to be impacted by mesh density, the finer the mesh the closer together they are. Think of the nodes as direct claculated values and the elemental as the average of all of the nodes. If the mesh is fine enough there is no difference, but it takes more computer solve the finer the me...
