Post CFX Update failed for the Solution component. SEC crashed?

Dear colleagues,

I am trying to use CFX to simulate the incompressible steady-state turbulent flow inside an S-shape duct. I used K-epsilon model with medium intensity, fully developed inlet boundary conditions from a straight channel at the same Re=13800, two walls with a non-slip condition, an outlet with a prescribed reference pressure of 2*atmospheric pressure (it shouldn't matter since I am using water as a fluid, not air), and two periodic boundaries which I set in 'Translational periodicity' in order to have an infinite duct in the spanwise direction.

For some reason, when I run the simulation, it writes a .res file and in the .out file there is no warnings or errors BUT I can't open the .res file.

When trying to open it, ANSYS Workbench comes with an error: 'Update failed for the Solution component in CFX. Solve ended with a nonzero exit code of 1, this could mean that SEC crashed due to an exception or when using Component RSM to a Cluster, that a Cluster command failed or it could mean SEC's non-zero solver exit code reporting mechanism is broken and the solver exited with a non-zero exit code.'

I also tried to use CFX as standalone in case it was a Workbench problem, but no luck in that either. I also tried opening the .res file using Fluent and it did not work either.

I have been trying changing several things on the simulation, but after several days trying, right now I find myself a bit desperate.

If any of you could help me, I will greatly appreciate it!!

Thanks a lot =)

Are you sure? Workbench told you that solve ended with non zero error code. This means that solver failed. What is in out file?

Thanks for your reply Antanas,

Unfortunately, I am sure there is no such a message in the out file. All it says at the end of the run is:

+--------------------------------------------------------------------+
| Job Information at End of Run |
+--------------------------------------------------------------------+

Host computer: ______
Job finished: Wed Dec 07 17:42:10 2016

Total wall clock time: 1.354E+01 seconds
or: ( 0: 0: 0: 13.545 )
( Days: Hours: Minutes: Seconds )

End of solution stage.

+--------------------------------------------------------------------+
| The results from this run of the ANSYS CFX Solver have been |
| written to ______________ |


I searched for errors or warnings, but none are present in the .out file. In the error message in Workbench it only sais that the non-zero error code could be a possibility, not that it actually is.
Any other idea?

Thanks

Have you tried to open res file in CFD-Post?

I did try, I am sorry I forgot to write about that. When I try to open it with CFX-Post, this error comes: 'ERROR
Error reading file '.../Turbulence/Project/GeometryTrial3_files/dp0/CFX/CFX/CFX_001.res':
Error reading number of domains (G/NZN).'


Does it sound familiar? I tried re-naming and re-defining the domains in CFX-Pre, but it didn't get better.
