Class 3 Error
If you have more than one fluid and you specify Cartesian velocity components for a specific fluid on an Opening boundary condition, then the simulation results may not be what you expect.
Fluid-specific Cartesian velocity components on openings are always applied in the rotating frame of reference, regardless of the Frame Type specified for the bounda
Specify the velocity components in the rotating frame of reference.
