0e24ed6342 [FEM] pipelines: distinguish stresses (#7246) 
- it seems using the same Field name for a vector and a scalar result causes problems with ParaView, see https://forum.freecadweb.org/viewtopic.php?p=601775#p601775
 therefore rename the vectors

876b4ebb8e [FEM] Elmer: fix flux equation 
- the Flux solver must be executed before Heat and Electrostatic
- the analysis can have multiple Flux equations -> write a unique solver name to case.sif
- the Flux equation can currently only take 2 possible values. Therefore provide them as enum

040f86c4d5 [FEM] fix body heat source constraint 
- as the name implies, it must be possible to set the heat to different bodies
- for this a selection dialog is necessary
- check that heat is not zero

0a18346767 [FEM] potential constraint: change default value 
- in practice one wants to apply potentials to faces via this constraint, therefore enable to set a potential by default, also assure that the initial unit is V

32d7663e46 [FEM] permittivity: improve code

9db5dff744 [FEM] fix handling of vacuum permittivity 
- fix message that permittivity object was not handled
- set an expression, otherwise the user gets only "0.000" for the default of 8.8e-12
- use as unit the common "F/m" (this is also more user-friendly than "s^4*A^2 / (m^3*kg)")
- fix a ToDo

e2636b2926 [FEM] Elmer example: remove wrong permittivity 
- a permittivity of 1 F/m is not physical, also not for testing. In fact overwriting a constant is not good practice for an example

dce15245fa [FEM] Elmer: handle pressure for fluids

52b3c75eb4 [FEM] change default pressure 
- a default of 1 GPa for a pressure onto a face is not suitable. use 1 bar (100 kPa) instead

335196a468 [FEM] [skip CI] remove an obsolete comment

a2e473c5b7 [FEM] Elmer: set constraints for solver systems 
- set constraints according to the Elmer docs (no conversion necessary, existing properties just stay integers)

b6cb5ffe4a [FEM] Elmer: fixes for multi-threading 
- load the results depending on the used cores, not always the multi-thread results
- avoid unnecessary console output - this info is already output in tasks.py
- handle number of cores as int to save in total 2 conversions

08af39c1a8 [FEM] Elmer: fix heat flux handling 
- the heat flux in the temperature constraint is not the heat flux from the heatflux constraint. The latter is in W/m² while the first one is W/mesh node

Uwe
2edf6abb2f [FEM] Elmer: add support to turn off solvers 
- with this property the linear solver is turned off. As consequence one can this way also disable the execution of an equation without the need to delete the equation object

- also add missing preconditioners

b716644e27 [FEM] Elmer: fix handling if fluids + solid materials 
- as already reported in the forum, it was not possible to make a flow simulation when there is also solid material.

bd796c9197 [FEM] Selection: fix error for 2D shapes

ed3625a0e0 [FEM] Elmer: allow lower relaxation factor 
- despite the Elmer docs say 0.01 is the lover limit, for fluids like water, one might need down to 1e-4

c219134a1e [FEM] Elmer: fix material bug and improve material handling 
- for fluid material writing the elasticity solver failed with unknown Young Modulus
- fix regression with checking for fluid material. Checking the material of the bodies is not sufficient. One can e.g. have a solid without bodies defined, then it applied to all bodies and there might be a fluid defined for only one body. Checking the body's material would then deliver there is no fluid

baaa5f8dd1 [FEM] Elmer: set constraints for relaxation factor 
- the relaxation factor is crucial for nonlinear systems thus help the user by setting constraints and convenient steps.
Since the property stays a float no update is necessary, existing properties just stay a normal float

48a206e3e4 [FEM] Elmer: notify users about missing fluid material 
- it was often unclear when no flow equation was written to the case.sif (was a regression FC0.20)

5cd06b6148 [FEM] fix bimetall example

69efa37e49 [FEM] Elmer: automatic update for BiCGstablDegree

4b2a486d51 [FEM] fix selection issues with flow velocity constraint 
- same fix as commit 7e071623 for flow velocity constraint
- the used selection widget did not highlight the selected faces. This made it very hard to work with when one has an existing document where e.g. 5 faces have a certain velocity and you cannot figure out which ones.
To fix this use another selection widget
