ff802c7274 FEM: elmer solver writer, add some comment in the regard of units 2022-07-12 11:35:45 +02:00

8afc5d3f0a FEM WB Elmer viscosity bug fix. 
In Elmer there was errors "Viscosity not found" if used mixed solid and flow calculation.
This fix disables Stokes-Navier eruation for Solid objects.

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.

ebc0c0ae04 [FEM] fix broken Z88 part 3: don't hardcode memory 
- we must not hardcode the number of stiffness matrix places, especially not for the Cholesky solver
The user must have a chance to change this setting in case of a solver error. This is also according to the Z88 docs that says it is a two step process:
- the solver first computed the necessary places
- the user must set the value accordingly in case it is too low

- also some code style fixes

d035bbc1ca [FEM] fix broken Z88 part 1: don't hardcode solver 
- especially don't hardcode the choly solver that fails quickly for finer meshes
- setting sorcg as default since it shows the best performance with the cantilever tests

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)

4a7f7a0faa [FEM] fix the Elmer solver writer 
- fixes #6604
as it was, Elmer was almost unusable because most values were input with wrong units to Elmer.
Elmer uses pure SI units

ToDo: fix the still wrong Vacuum permittivity

5f4b87035b [FEM] Add tools for more yield points in simple hardening materials 
String List instead of String should allow for arbitrarily many entries,
theoretically.

Note the defaults previously in `YieldPoint1` an `YieldPoint2` were arbitrary.
Now the list is kept empty by default.

Fixes issue #4720.

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.
