* FEA: fix 1d beam cross section orientation
* FEM: revert 1,2-directions to FreeCAD way; fix normal direction for z<0
* FEM: change 1-direction to +y axis
Previous commit changes the 1-direction to -y axis, however originally it was directed at +y axis. This commit makes the 1-direction face +y axis
* FEM: update cantilever tests
* FEM: relax math.isclose by adding abs tolerance
- fix bug that changing constraint type in dialog lost flux value
- accept and not immediately save any changed value
- make the temperatures a PropertyTemperature to get rid of hacks
- also fix some too long code lines
- the current implementation only considers explicitly given binaries (with full path) and ignores the setting to check the environment paths
- also remove 2 trailing whitespaces
- for the first time ever you get now for every time step a result in FreeCAD
- this way also change output filename prefix to "FreeCAD" to avoid we depend on the default name Elmer gives and that was already changed in the past and to distinguish the *.vtu files from those created e.g. directly by ElmerGui
- also remove an unnecessary output to the case.sif file
- different time results were never output, only the final one
the reason is that the Output Intervals intervals property was missing
- a second reason was that the result scaling solver must be executed every time an output should be generated
- the BDF Order property is a transient-only property
- different time results were never output, only the final one

- a second reason was that the result scaling solver must be executed every time an output should be generated
- the BDF Order property is a transient-only property
- fix bug if no solver should be default
- only provide solvers that are available to be the default
- also add commit opened transactions
- also remove unused include and correct an include
- 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
- 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
