- 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
- same fix as commit dc851bd8 for flow velocity constraint
- the used selection widget did not highlight the selected faces. This made it very hard to work with when one has an existing document where e.g. 5 faces have a certain velocity and you cannot figure out which ones.
To fix this use another selection widget
* Add Placement::isSame() and expose to Python
* Add Placement::multRight/Placement::multLeft
* Fix PlacementPy::rotate
* Add Rotation::multRight/Rotation::multLeft
* Add a test feature FeatureTestPlacement for uni tests
* Add unit tests
Documentation for Placement.rotate() claims this function would be
compatible to TopoShape.rotate() which isn't exactly correct as the
generated placements differ because of backwards multiplication.
This commit adds a "comp" (as in "compatible") keyword argument that -
when "True" (default is False) - produces a Placement that is interchangable with the one
that is generated from TopoShape.rotate().
- (a regression to FC 0.20.0), use new settings ("direct" is already the default, iterative solving takes here about 5 times longer, DisplaceMesh must be False)
- 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
- since our mesh is in mm, we must multiply the set factor by 1000 to get the real factor. This applies also for pipelines from CCX results.
Now the factor fits with the factor one can set in the CCX results dialog
