Hey guys

Got a problem when i was doing a fluid sim today - I setup everything in CFX pre then go to the CFX solver, windows with error messages poped up as * below.

I guess it cause be incorrect parallel setting because the calculation was find in serial mode.

* The ANSYS CFX solver could not be started, or exited with return code 255; .No results file has been created.

* CFX_003 has terminated with errors. Run concluded at: "date"
No results are available

* Update failed for the solution component in CFX. The solver failed with a non-zero exit code of : 2


Any feedback will be appreciated

PS: the same task was run normally on my old computer @ e5 3470, but lately i upgrade to a E5 server with 20 core, 32GB ram to go faster, the setting and everything else were the same.

hi Cyrus ,
i suggest to you to
1-check the mesh
3-if the problem transient ,check the total time you entered
2- re setup the problem and save the project before running OR make a new project with the same parameters and settings
i face this problem when i make changes on the the setup and make run , this massage appear after a few iterations , but when i make a new project the problem is solved.

The problem was solved by redoing all the project from modeling, that was whole bunch of work but finally solve the problem.

thank you very much for help.
