I just install the Fluent(12.0.1) and after I open the Fluent at the first time in single mode it can use but after I open in parallel mode it have error

Host spawning Node 0 on machine "user-PC" (win64).

You can press CTRL+C to stop the startup process!

check your firewall settings. It's likely blocking the mpi from executing. Maybe even antivurus software.

mpiexec is having trouble launching the specified mpi for Fluent to run in parallel mode. If the firewall/antivirus is not actively blocking it from executing, then it must not be there. From the output, it looks like you are using msmpi. I don't think this mpi is pre-packaged with the Ansys installation. Can you check if this is installed on your machine?

Also, try using another mpi. I think there is an intel, and pcmpi is usually supported by most platforms. There is also mpich/mpich2. The Ansys installation package also comes with an hp one I believe.
