fluid zones

Fluid zone models (e.g. porous, actuator disc).

TypeWhat it is
momentumMomentum source fluid zone.
rotatingA rotating frame on mesh cell zones (MRF); the mesh stays still.
discActuator disc fluid zone.
porousPorous media fluid zone.
canopyCanopy model fluid zone for atmospheric boundary layer simulations with vegetation.
ablAtmospheric boundary layer fluid zone, applied to the whole mesh.
idw transformInverse Distance Weighting transform fluid zone.
rbf transformRadial Basis Function transform fluid zone. Full RBF when base_point_fraction=1.0 (default), Multiscale RBF when base_point_fraction < 1.0.
