open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I just tried activating the CHECKING THE MESH option in Telemac-2D under v7p1r1. Everything seems to work fine in scalar. But when I switch on the parallel mode with CHECKING THE MESH option enabled, the program crashes. I should say if CHECKING THE MESH option is disabled, the simulation works fine in parallel.

The hint in the listing is that node 1845 is a point that has two neighbours. When I inspect the global mesh near node 1845 I don't see the problem (attachment 1). But, when I display the partitioned mesh near node 1845 (attachment 2), I see the hint of the problem.

Does anyone know why the simulation halts in parallel under this case? I couldn't figure out the checkmesh.f subroutine to know why.

Thanks,

Pat

Hello Pat,

Glad to read from you.
This is clearly (most probably) a bug with the parallel mode. What is the crash error message? Can you send me the model to check it up?

with my best regards

Hi Riadh,

Thanks for looking into it. I will send you the files via email.
