Using MRFSimpleFoam, I've simulated the forces on a co-axial helicopter rotor system. However, I would like to view the airflow induced by the system. I'm working in 3D and using actual rotor data for the mesh using blockmesh. I've tried many things, nothing as worked for me. How can I view the the changes to the atmosphere caused by my rotor? Here is 2D picture of the rotor, just to give an idea of what it looks like. Keep in mind it is a 3D mesh. I lowered the quality of the mesh to decrease simulation time. Thank You.

I'm using pimpleDyMFoam, I changed to a single rotor for now. The rotor is in a cylinder with 2 inlets (top and bottom). Everything else runs fine just no induced flow. Could someone tell me what I'm doing wrong? The don't really understand the fvsolution and fvshemes, I taught myself OpenFOAM, so I'm still learning.
