Hello, i saw this tutorial: 

in youtube, but i can't do the final part, the solution, because those errors appears: "The ANSYS CFX solver exited with return code 1. No results file has been created." and "Update failed for the Solution component in CFX. The solver failed with non-zero exit code of 2". Can someone help me, please?

Denis, this a very generic error that appears in CFX-Solver. Can you attach your workbench archive file so we take a look at it? If you're not sure how to create and share a workbench archive file, please refer: Saving & sharing of Working project files in .wbpz format

Thanks for response, Rahul. I'm trying attach the archive, but when i choose the file and i click in upload, the archive don't is upped. The archive size is 96MB, and i don't know why this it's happening.

Denis, I looked into your setup. Your global coordinate system is not located at the center of the rotating domain and since you were defining the rotation about the Global Z axis, you were getting the error. If you're just learning from this tutorial and don't want to go back to the geometry or mesh and fix the global coordinate system, you can follow the steps mentioned below that will help you fix the error and run the simulation. All you'll be doing is going to the CFX-Pre setup and defining a new coordinate system "Coord 1" which would be centered at the rotating domain. You'll then define the rotation w.r.t this new coordinate system. And your rotation speed (1500 rad/s) is really high compared to the value used in the tutorial (300 rev/min). So your timescale might be much smaller than that shown in the tutorial.
