- 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.
- 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.
- currently one can enter any path for the solver executables, a check is missing
- moreover for Z88 the executable name is error-prone (just happened to me and cost me half an hour to find out what is wrong), therefore check also the correct filename. For Elmer this cannot be done since there are different executables one can choose of (e.g. for multi-threading etc.)
- in the preferences one could specify more CPU cores than available
- also correct a label sine the number of cores are since FC 0.20 used for all CCX solver runs
- also remove unnecessary (doubled) slots from the UI file
- since a while ThermalExpansionCoefficient is used, VolumetricThermalExpansionCoefficient is only used for the material task panel
- as already stated in a code comment, the unit of VolumetricThermalExpansionCoefficient is ThermalExpansionCoefficient, therefore we must check for ThermalExpansionCoefficient
- we must also check if ThermalExpansionCoefficient exists
- Adapt the existing fluid material cards to use the ThermalExpansionCoefficient
In Elmer there was errors "Viscosity not found" if used mixed solid and flow calculation.
This fix disables Stokes-Navier eruation for Solid objects.
modified: src/Mod/Fem/femsolver/elmer/writer.py
Following the law of Demeter add some wrapper methods to PropertyGeometry and implement them in sub-classes. As a side-effect this makes some const_cast obsolete
* refactor TaskPostDataAtPoint::on_Field_activated()
* show results in a label instead of message box to reduce clicks
* in output window also print field and position as the pure values are useless
