Hello, I am doing a steady simulation of compressor blade. I build the domain with 2 IGV and 1 blade. I want to simulate 2 passages which include 4 IGV and 2 blades. I use the copy mesh command in CFX-pre and define all newly appeared surface in correct boundary setting. When I start the simulation. It always crashes in the beginning of simulation, showing error: zero divided. I check the setting in the CFX-pre,all seems ok. And the single passage simulation works well. I do not know what I did wrong in the process. Could anyone shear their experience on this issue?

First read the FAQ on this: https://www.cfd-online.com/Wiki/Ansy...do_about_it.3F

Check that your second mesh region is properly connected to the first and there are no gaps or slivers.
