Periodic boundary conditions for moving reference frame (MRF) simulation)

Hej!
I'm new to starccm+, trying to set up a moving reference frame simulation for a hydrodynamic bearing (spiral groove bearing). Since I don't want to simulate the whole bearing (too high computational cost), I imported the geometry of only 36°-part, which should be rotationally repeated (10x). With tutorials I got as far as setting up periodic interfaces for the boundaries... Does anyone have experience on which physics conditions/values I have to set for the periodic interface? The fluid should not be driven by a pressure jump or mass flow, but just by the rotating part (i.e. the part in MRF) above the bearing. I did try it with setting the pressure jump to 0.0Pa (zero), but the simulation didn't converge... Thank you! |

Hi
Periodic boundaries are used to mirror the flow fields from one boundary to another amongst the boundaries in the interface. They do not need any physics condition per se. I guess you are trying to simulate 3d axisymmetric case where I do not see any moving reference frame fitting in the bearing simulation. |
