I was exploring the heat exchanger tutorial,
OpenFOAM-2.2.x/tutorials/heatTransfer/chtMultiRegionSimpleFoam/heatExchanger After launching the ./Allrun and opening the resullts in Paraview, I was expecting to see the rotor blades spinning around but.. the blades don't move! And the streamlines go through the blades Why? My thinking: Maybe what do we see is not the actual position of the blades? They are just symbolically represented. In Paraview you just see what they cause inside the fluid, with an RPM specified in system/air/fvOptions (MRF1 subdictionary). The streamlines do not go through the blades because they are in another position that you don't see. That's why the streamlines don't seem to turn around. It is correct? Or Am I just making a big misunderstanding? |
