CFD Online Discussion Forums - Problem with parallel run of my solver based on pimpleDyMFoam

Dear foamers,

I have not so much experience in MPI, I would say, I don't have it at all :)

Writing a new solver, based on pimpleDyMFoam, I met some problems with the parallel run of my case..
Solver is finished and work well when running on a single core, but parallel calculation doesn't work and is accompanied by infinite series of error messages like

Code:

...

Starting time loop

Than this peace is repeated infinitely until I stop the process by ctrl-C:

For me the message is absolutely unclear, and I have no idea, where to look for a bug in my code.. May be, some of you have met such situation?

Yeah, as you can see from the output, I am using OF 2.2.1, compiled on a macbook running under Mountain Lion :rolleyes:

Thank you very much in advance for you time!

Best regards,
Oleg
