- also fix a typo in test_object.py

d2ec8a85cc [FEM] Elmer output material name 
- when looking at the Elmer input file 'case.sif' it is extremely helpful to thee also the name of the material
  Since the name is only form info, this does not change the actual simulation

3818534cd6 [FEM] Elmer: fixes for the simulation parameters 
- output equation-specific values only if this equation is used
- use Elmer's default for BDF order as default for FC too and allow to change it
- don't hardcode to Steady State. Transient must be possible too, this way add parameters to run a transient analysis

96ba47e80f [Fem] Elmer: add missing settings for the stress solver 
- the usually mandatory setting DisplaceMesh was missing leading to imprecise results. Now the calculated faceload is almost the exact same as with CCX
- also add most of the other settings Elmer 9 provides
- also add tooltips

ba858175fe [FEM] Elmer: use direct solving as default for stresses 
- direct solving is sometimes even 10 times faster (as fast as CCX) and as accurate as CCX

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.
