DAFoam v4.0.3 UAV_Propeller tutorial Issues

[xgd2552]

Hello, DAFoam community,

I'm trying to add MRF (Multiple Reference Frame) angular velocity as a design variable in UAV propeller tutorial. The add_dv_func method mentioned in older examples is not available in the current version, and I need guidance on the proper approach to implement this functionality.

The missing piece is how to make the MRF value actually update the solver's primalBC option during optimization iterations. In older versions, this was done using:
self.hover.coupling.solver.add_dv_func("MRF", MRF)
But this method is not available in the current version.

What is the recommended approach in the current DAFoam version to implement custom design variable functions that modify solver options?

Thank you

Right, we deleted the option to use the rotation speed as the design variable. You have to add it back manually. Check: https://dafoam.github.io/developer-guide-add-features.html
