- same as #8963 but for initial velocity
- add an example file that demonstrates the influence of the initial velocity
- some fine-tuning for the existing flow example
- complete revision of the constraint.
This is a breaking change, meaning existing constraints won't work.
This is possible because since 2 days ago the whole flow equation did not work at all. Also the existing constraint implementation if buggy and cannot be used to do the Elmer tutorial. Also, the constraint is only used by Elmer and only be the flow equation.
Since nobody complained about the obvious wrong results, we can assume the flow equation was not yet in practical usage (and for FC 0.20 we known that it does not work at all, first with FC 0.20.1).
It is necessary since it must be possible to either input a velocity or an equation. With an equation, a velocity profile can be specified.
- update the flow examples accordingly:
-- simplify them since an initial and and output velocity is not necessary to specify
-- use a formula as input velocity for the non-turbulent example
- Elmer offers the "Variable" calls do define variables via math equations. These are for example used to define as constraint a certain velocity profile
- the message how to use the feature is not useful since it is triggered by the GUI selection and in the GUI has already the info in form of tooltips how to use
Due to a flaw in the QUiLoader, UiLoader were loading all designer plugins
it can find in QApplication::libraryPaths(). This in general a bad
practice and leads to bugs due to some plugins may perform some unexpected
actions upon load which may interfere with FreeCAD's functionality.
To avoid such problems reset the libraryPaths before creation of a
UiLoader object.
Also move setLanguageChangeEnabled(true) into constructor due to it's
called every time it's being instanced anyway.

This should fix this (I cannot reproduce it):

Lately I added the geometry pointer to the item. This has indeed
the potential for an already deleted pointer being accessed.
This PR removes the geometry pointer from the item and relies on the
ViewProvider to indirectly access an updated pointer.

Support for moving external geometry to another layer will come in the future.
This commit adds the ability to shift the involute profile inside or
outside. Profile shift is implemented as coefficient, i.e. normalized by
the module, so that it the whole profile scales with the module without
chaning shape.
To verify the profile, the tests implement an "over pins measurement"
using formulae found in literature.
Backward compatibility with FreeCAD-v0.20 is garanteed by already
existing tests, not touched by this commit.
This addresses issue #5618.
- the heat capacity of water was wrong
- also specify just thermal expansion, this make that water is recognized as material and then all water parameters will be available
(that the analysis fail despite CalculiX reports everything went well s is another issue, I will investigate later)
