- 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.
========================================================================
The NotificationBox is extended to take the QRect in global coordinates. Then
it will try to dimension the label within this area. If a fixed width is provided, that
is enforced (take precedence).
The NotificationArea passes the QRect of the main window to the NotificationBox.
This is intended to fix:
https://github.com/FreeCAD/FreeCAD/issues/8940
- 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
