Which version of Fluent are you using?

The problem is likely an mpi fault. Make sure your Fluent & mpi version are supported in windows 8. To check if it's an mpi error, run in serial mode.

Another reason could be overclocked ram which is unstable.

Hi bros,

Thanks for answer,

Yes I was investigated on this way, problaby they is a problem with win 8.1.
I'm running Ansys fluent v15.0 v15.7 v16, problem appear for each version.

I will check my mpi version and try to run a serial simulation. If it's running in serial without problem, what can i do ?
