This run of the ANSYS CFX Solver has finished.

any help???

Try to look into the monitor, there could be some hint to what seeting needs correction
Edid: a friend said to me it could also depend on the parallel settings, as well as when you use a processor of the Intel i-series there seem to be some problems because the i-series uses virtual cores what messes up the memory control or so

Fluent runs good in parallel but dunno why cfx doesn't!!
btw which is better CFX or Fluent?

Samer - CFX runs fine in parallel. Something is wrong with your setup. And general statements like "what is better CFX or Fluent" will not get a useful answer.
