MultiPhase Simulation of Pump

Altair Forum User

Hi All,

We are trying to simulate the fluid flow through pump using AcuSolve Multiphase simulation capabilities.

Using Sliding Mesh approach, fluid does not enter into the rotating interface zone.

Where in case of MRF approach, we are facing convergence issues even for small deltaT.

Would it be possible to upload the .inp files? and a screenshot of the geometry. If fluid is not entering the interface surface, it probably means some issue with assigning 'boundary condition' or interface surface.
