e76fbe6998 [FEM] fix CCX (new framework) binary handling 
- when the binary was not found, the function called the non-existing binary
- also push error message to the status info so that user gets feedback also when report view console is not shown

1ba44fb1ca [FEM] fix Z88 binary handling 
- when the binary was not found, the function called the non-existing binary
- also push error message for Elmer and Z88 to the status info so that user gets feedback also when report view console is not shown
- uniform wording to 'binary'
- avoid unnecessary console output

eec258ab37 [FEM] enable to run Elmer multi-threaded 
- this needs proper testing, especially on a non-Windows system

- note that for some tasks multi-threading requires non-standard additional solvers like MUMPS. Ideally the user should be informed about this, depending on the equations he uses. But this should not block this PR, meaning to use multi-threading in general.

3a3a20da46 Replaced python2 usage of next() 
iterator.next() is deprecated in python3.
next(iterator) is the direct replacement.
In some cases a for() loop makes more sense

33a769a426 [FEM] fix solver console bugs 
- for Elmer and Z88 on Windows several windows pop up (console windows). This is maybe annoying and the user is wondering what is going on, but the main problem is that when you close them, you break the solving process.
Therefore, on Windows only, hide the empty popup windows.

6eae0c021a 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.

fdd103814c [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.

f88c95d743 [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

e9835c0b10 [FEM] fix broken Z88 part 1: don't hardcode solver

- setting sorcg as default since it shows the best performance with the cantilever tests

80ad680dc9 [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)

12a07760e9 [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

16a82d1eb7 [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.

0a91d2e731 [FEM] Change reference files to avoid failed tests 
Fixes two errors introduced in/due to 7621382272ae712ebf4493d996d1a1a918e95df7.

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.
