Some parts of `DrawSketchHandlerBSplineByInterpolation` were taken from
`DrawSketchHandlerBSpline` but not modified to reflect the differences.

Specifically, when drawing by interpolation, only cubic splines are currently
supported.
Some related "TODO" comments are also removed or modified.

Only creates 1-degree splines by describing knots.

- for e.g. the solver objects it is important that the added equations are visible in the TreeView
- also improve activation of analyses for documents with multiple analyses: one activates one and can then subsequently add an object to it because the activation will also select
- this PR addresses a long-standing annoying issue: You are already in the FEM WB and load a file.
Then you cannot just start but first have to activate the Analysis. But one is in the FEM WB to work with analyses.
- for e.g. the Elmer equations it is important that one can add several equations subsequently and that the added equations are visible in the TreeView
- the spring constraint is currently unused but it can be used for Elmer mechanical analyses
This PR does so and also overhaul the dialog UI.
- use the spring constraint also in an example file
- add fields to specify a formula for the displacement, this is necessary to make transient deformation analyses with Elmer
- add option to set displacement from result of flow equation
- this way also a major overhaul -> simpler dialog logic etc.
- fix whitespace in the SIF writer
- Elmer GUI uses only 20 nonlinear iterations, so we should do the same (500 were also not sensible)
- don't restrict nonlinear-Newton iterations to 100, 500 might be necessary for turbulent flow
- update author
- adds new equation "Deformation" (this name since the stress solver got in FreeCAD the misleading name "elasticity")
- this way change icon of elastic solver to make the difference clear
If the MTEXT exceeds 250 characters, the contents are broken up into
several records in the DXF file. The C++ importer has been changed
to collect all these pieces into a single string containing all the text.
- use a more sensible velocity distribution
- change inlet temperature for 2 examples
- also change step size for nonlinear iterations for more convenience for practical usage
- 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
