open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear all,
I user Tomawac model in parallel mode, version v8p1r1. My domain has 176721 unstructured triangle element. The program runs seem correctly when I declare to use 7 processors. Unfortunately, the program was fail when I use more than 7 processors (for example: see attached information when I use 36 processors). Thanks you very much in advance for any helps or suggestions.
Best regards

Hi
As it's at the first step this probably means a problem in the partionned mesh...
You should investigate this point for 8 processors (for example) and identify which processor fail and then which subdomain is concerned.
You could also look for the 36 processors. Maybe this will guide you to a smaller subdomain where a problem in input data exists.

Regards
PS: without any file and only a small message it's hard to help you

Hi,
Thank you very much for your prompt response.

Dear Mr C. Coulet.
I don't know why the program runs seem correctly when I use 7 processors (simulation for one month) ?. If my mesh has a mistake I think that the program will be fail at the first step too when I use 7 processors ?. Thank you for your advise.

Just for information! I use the same mesh for Telemac 2D et Sisyphe, I don't have any problem with the number of processor used.
