Hi Dear All
I can not run my case in parallel while I've run the case in serial with no problem.
the geometry is pipe with length and diameter equal to 4m and 0.025m in order.

the Error :

maybe the problem is that some where division by zero is happen because of poor mesh quality.I've generated the mesh in following manner:
(110 10 10)

your help is appreciated.
Thanks

Hi,

Are you able to successfully run your solver in parallel if you change the decomposition method?

Hi Dear Fumiya

no, I've changed the decomposition method , once I've selected simple method and another time hierarchical method but I was not successful .

[AmirBaqa1987]

nobody can help !!!

Greetings to all!

@Arjang: Well... it's possible to help you, but not with just this little amount of information . To understand what I mean, read this: http://www.cfd-online.com/Forums/ope...-get-help.html

Because from the output you provided, the only thing that can be seen is that:

1. There was a SIGFPE: http://en.wikipedia.org/wiki/SIGFPE#SIGFPE
2. It occurred in:

   Foam::PBiCG::solve

And that's it. There is nothing else that can be deduced from this output!


So, given the amount of available information, the only suggestion I can make is this - read this page: http://openfoamwiki.net/index.php/HowTo_debugging

Best regards,
Bruno

Thanks Dear Bruno
I've solved the problem by using your tip.

the problem was with mesh quality.

best regards.
