Hi, i am doing a flow cavitation analysis on a centrifugal pump impeller (closed type). There is a tutorial on ansys cfx about it, but the geometry of my impeller is slightly different. the thing is that in the tutorial, the simulation is done only on 1 blade (by this i mean the enviroment around one of the blades) and it does not have information about the diffusor or why they ignored it, and i dont know. besides, i am using ansys cfx 12.1(i am new in this) and can't find how to choose two points for the rotation axis, i mean, i have found the tab to allow the two points option, but when im going to choose the points, i cant snap the cursor to the edge i want. i would really apreciate help in this case. THX!
P.D. some tips for the mesh refinement? i am using the hexaedral method. |
