Dear cfd-onliners,

i've got this boundary mesh very simple, a cube in Tgrid.



The tet generation just doesn't work. error is "duplicate nodes", why is this happening, how can i solve it ??

Thanks a lot

The mesh file is here:

Ali there are two solution.

1. Get good mesh for Tgrid from ICEM OR

2. Repair manually the problematic nodes.

i don't see what is wrong with this mesh. In icem, i generated shell mesh using delaunay for each surface individually. there is a distorsion in the size of the elements because i forced it to match a curve bunching law...

Also in icem sometime when generating the delaunay after the octree it gaves me an error:

Application did not finish correctly.
Error: tri2tet exited with a non-zero status

Any idea ?

i think the problem comes from the curves's node distribution... just check with a normal cube and it works
