Hey guys,

I've sent this error to ANSYS's customer support, but they love to take there time on responses. So I'm reaching out to you guys to see if I can get an answer quicker.

I have quite a large mesh (13.6 million cells) and am trying to run a CFD solution using FLUENT v12.1 on an 8 compute node parallel Linux cluster. Each machine has 4gb of ram.

When I run the FMG initializer, it will solve for each stage. At the completion of the ininitialization I can a series of textual output about an issue with the MPI communication. I have attached a screenshot of the error messages.

Anybody know what might be occurring and how to correct it.

Thanks in advance.
