error message cfx solver

The solver stopped my simulations after 49 timesteps given the following error message:

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

I've changed the the wind velocity from 32m/s to 20m/s and try a second time, but the solver stopped after 46 timesteps.

However,when I ran another simple tutorial example ,the problem did not happen.

I wonder whether there are problems in mesh.Here are the datas.

DeterminantMin = 0.782659, max = 1, mean = 0.962677437883
268122 elements with the "Determinant" diagnostic
559433 elements for which this diagnostic is undefined

Aspect ratio:0.00331543, max = 349.772, mean = 11.1167417468
746314 elements with the "Aspect ratio" diagnostic
81241 elements for which this diagnostic is undefined

miniangle:Min = 0, max = 90, mean = 44.4654433844
827555 elements with the "Min angle" diagnostic
0 elements for which this diagnostic is undefined
thanks in advance

Can you post the output file? The snippet you show is not very useful.

I suspect the problem is with writing results files, but that is just a guess.

which format of the file? def, tin ,ccl?

CCL or output file. They are text files and should be small enough to post on the forum (possibly as an attachment).

The cfx5 file is a meshing file. Discuss that issue on the meshing forum - but the error message in the file is pretty clear.

I cannot see anything too unusual in your CCL file. You have not included the solver out file.
