Obi is based on PBF (position-based-fluids), which is a very simplified fluid dynamics model. It isn't even close to the level of commercial engineering-grade CFD solutions, as it makes lots of assumptions that favor performance over correctness. It can only model newtonian fluids (and even then, using an extremely simple, isotropic viscosity model), and centrifugal forces aren't taken into account.
It's not intended to be used for cases such as the one you describe: it's only meant to provide fast, physically plausible fluid simulation for games.
Dear josemendez,
thank you for the quick answer. I have already assumed that, but I thought it does not hurt to ask.
Have a nice weekend.
