Hello,
I'm trying to simulate an airfoil subjected to a parabolic inflow.
Is there a way to define an equation for the flow velocity constraint in Elmer Solver?
In the Freecad interface, anything other than a number is apparently not allowed

If you want to simulate the flow of air around an airfoil, try the CfdOF addon workbench. It's really powerful and well implemented.

You must edit the sif-file after case writing.

This is precisely what I needed. Thank you!thschrader wrote: ↑Tue May 17, 2022 7:16 amYou must edit the sif-file after case writing.

Hello @ziz , I just implemented direct support to enter equations to the velocity constraint dialog: https://wiki.freecad.org/FEM_Constraint ... y#Formulas
This feature will be available for the next major FreeCAD release but you can try it out right now if you are on Windows by using this installer:
https://github.com/FreeCAD/FreeCAD-Bund ... taller.exe
or next week with the next weekly builds for Linux and MacOS: https://github.com/FreeCAD/FreeCAD-Bund ... kly-builds
Note: when you use a weekly build you must recreate existing flow velocity constraints.
In the https://wiki.freecad.org/FEM_Examples check the flow examples as they use this functionality.
