open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi everyone,

The basic information is as follows. A 2d domain is setted up and could be run normally, then the mesh was refined around my study area and all releated files were updated. Then for the new mesh, the computation stopped at the beginning of the run, the sortie file was written in the end of this post. I only konw it stopped when calling s.r. inbief, but I don't know how to find out the exact problem, where could be the problem lie? May someone give me some advices? Thanks a lot!

Hello Viola

Probably you have a problem with the new mesh. It could be a problem of very small element or some superimposed nodes. This could be met when you have large coordinates and simple precision of mesh (truncation will generate nodes with same coordinates).
Anyway, try to add the new keyword CHECKING THE MESH=true (only with v7p1 version). Telemac will make a first checkup of the mesh. If it is not fixed, please send us the model, I will do it for you.

with my best regards

Hi Riadh,
Thank you very much, I will try it now following your advice!

Viola

Hi Riadh,

You are right, the new run told me this:
POINT 2003 HAS ONLY 2 NEIGHBOURS
POINT 2362 HAS ONLY 2 NEIGHBOURS
POINT 2751 HAS ONLY 2 NEIGHBOURS
POINT 2761 HAS ONLY 2 NEIGHBOURS
POINT 2789 HAS ONLY 2 NEIGHBOURS
POINT 3239 HAS ONLY 2 NEIGHBOURS
POINT 3438 HAS ONLY 2 NEIGHBOURS
POINT 4711 HAS ONLY 2 NEIGHBOURS
POINT 4907 HAS ONLY 2 NEIGHBOURS
POINT 5299 HAS ONLY 2 NEIGHBOURS
......
and I know how to fix the mesh now, thanks a lot for your help!
