Hi all,
This is a really basic question but I need to pose it somewhere to help me carry on with my job. I have started with CFD some days ago and as I am an advance user of mechanical ansys I've decided to use Ansys CFX to in a near future deal with FSI problems. Right now I'm dealing with cavitation problems in a NACA profile that I tested in a water tunnel, to simulate I draw the geometry in ICEM but now that I have to mesh I find some problems. Following the pipe blade tutorial I tried to do an o-grid around the profile, limited by tunnel faces but it makes several nonsense geometry blocks. I pick the blocks wich conform the blade and perform an o-grid around the blocks to be able to capture the boundary layer. Selecting the lateral faces to not to expand in this direction. Am I wrong? Thank you very much in advance! |
