cc4578e9ae [FEM] fix broken Z88 part 4: don't hardcode memory for iterative solvers 
- we must not hardcode the number of coincidence vector places
The user must have a chance to change this setting for the iterative solvers according to the Z88 docs.
We use as default the number Z88 uses in its distributed example.

b4befd14b3 [FEM] update Z88 tests 
(I doubt that it is sensible to check if a hardcoded memory value is written. The test will fail if you use a non-default memory setting on your FreeCAD. The CI uses of course the default)

389ae0ab39 [FEM] SI unit fixes for Elmer 
- since we use consistently SI units (as recommended my the Elmer forum), we need to scale the input mesh (we use ElmerGrid that has an option fur this purpose)
- Since the result will be in the scaled mesh, we need to scale it back

With this PR, one gets now correct result independent of
- the used unit scheme
- the simulation type (electrical or thermo-mechanical)

6c977d8511 [FEM] Change reference files to avoid failed tests 
Fixes two errors introduced in/due to c6697bbc78.

First one is a typo. The writer used "translations" where the reference file for
the test used "translation". Went with "translation" since that was mentioned in
the comment just above.

Second one is some missed out new lines in the reference file
`.../constraint_transform_beam_hinged.inp`. These lines were added in
`.../frequency_beamsimple.inp` but not here.

75371bb238 [FEM] add mesh algorithms 
- Gmsh has since a while 2 new mesh algorithms
- on the other hand the two algorithms ""Frontal Delaunay" and "Frontal Hex" are deprecated and not listed anymore in the docs: https://gmsh.info/doc/texinfo/gmsh.html#index-Mesh_002eAlgorithm3D
and indeed all attempts with these 2 algorithms fail
