- 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
- 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
- for an not yet known reason the result from Elmer are only for eigen analyses a factor 1000 (we send the mesh scaled to Elmer and it seems the eigen solver does not notice this)
Therefore scale these results
- after a simulation was run, the pipelines and its childs are recomputed but its shape coloring is not updated.
- also update XML documentation
- also remove comment in tasks.py for now
- it seems that we will need to scale result values (probably for the Elmer Eigen solver)
This PR adds the framework to do this. It is meant for Elmer but designed versatile.
- on recomputing scalar or warp filters the information about the field was lost.
This is because the validity of an array was tested before it is actually filled
- also fix MSVC warning of using a C++ keyword as variable
- also avoid an unnecessary recompute after Elmer solver was run
- one needs to specify a file when calculating the capacitance matrix
- add electric flux to point filter results
- add missing parameters
- also some sorting
- update tolerances also for existing analyses to fix the bug that users see e.g. "0.001" and not the actual used tolerance
- also a fix for new stress analyses
- also a formatting fix
- 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
- 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
- reverts commit d296732d - the scaling it correct
- there is a bug in Elmer that the heat source is not aware of the scaling
- write the scaling directly to the solver, not to the mesh itself. (make in principal no difference but we are closer to the solver)
- currently for Z88 nothing happens when clicking the Edit button in the solver task dialog. The reason is that opening *.txt files was never implemented
- also do this for Elmer
- for Z88 we need to open several file for a proper editing because the solver info is distributed over these files
- it turned out that despite not mentioned in the manual, ElmerGUI adds the Stabilize setting for all setups
-> bring "Stabilize" back for all equations
(for "Bubbles" it is correct that this is an equation-specific setting)
- enable the disabled options. They work and are according to the Elmer manual. The user is free to use them or not and since they are all False by default, existing analyses won't be affected.
- add two missing settings
- for new equations, enable at least one calculation, otherwise nothing will happen when an inexperienced user uses the default
- the mesh scaling was a hack to work around the fact that FC's mesh is in mm while all input units are in SI. It turned out that this made more problems than it solved because Elmer checks the length unit and makes internal recalculations. So the mesh must not be scaled when send to Elmer (despite the ElmerGrid docs doesn't state this).

- for BiCGstabl the minimal degree is 2, but 3 is recommended
- when adding the equation, it should do something, therefore enable the calculation of the principal stresses (as it was, nothing was calculated except of the displacement)
