open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

We are trying to run a model for the North sea and we refined our mesh to specify the coast of Belgium.
When we want to run telemac2D, it gives an error in the end:

Wrong number of segments

We attached the code of the program.

Can you help us?

Hello,

What happens is that STOSEG numbers the segments and the algorithm finds one more than the formula (3*NELEM+NPTFR)/2 which is the correct number, this could be due to some mismatch in the mesh, like two segments superimposed or 2 points superimposed.

With best regards,

Jean-Michel Hervouet

Hi
Another possibility is your problem comes from your mesh.
As it's written in the output file, the maximum number of elements around a point is 11 in your case. In telemac, the limit for this value is 10. There is some arrays which are defined with this limit so overpass this value could generate crash.

Hope this helps
