Hello guys!
I am doing a 3D transient simulation on VAWT on ansys fluent.

1) The Solution is completed successfully but I am not able to load CFD-post. When I update the tree and click CFD-post to open it, it throws me following error: I have also attached image file.

CFD-Post Application Error

ERROR
Error reading file 'C:\Users\rushi\Documents\fhjhj_files\dp0\FFF\Fluent\FFF.flprj':
Reason: The run contains transient output but no output files were defined.

Also When I checked the file in Fluent folder, I did find FFF.flprj. I am really not sure which "output files" the error is talking about. I am however able to load the cas.h5 files independently but it is useless since I was the transient results. I have also attached the parametric results screenshot.

2) I have not done too much of a dynamic mesh 6DOF problems in 3D. And due to this error I am not able to visualize the results. I have also uploaded the report.xml file just so that you guys can see my setup. Am I doing anything wrong? Will the turbine rotate?

Any help is really appreciated.
