open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I'm using Telemac-3D v7p1r0, hydrodynamics only.

I tried to obtain results of velocities U,V on a line defined by coordinates X1,Y1,Z1 and X2,Y2,Z2. To do that, I'm using the option FILE FOR SCOPE. I created a Fortran file based on Subroutine SCOPE.
It works well depending on the coordinates of the begin and end of the line.

For example, it works fine for this coordinates:
X1,Y1,Z1 : 316246 8973000 90.0
X2,Y2,Z2 : 318866 8973990 90.0

but if I add 1 meter to X1, say 316247, it stops working and shows the following message on the standard output (screen):

---

COUPE : THE CROSSING LINE DO NOT CROSS THE DOMAIN
X1,Y1,Z1 : 316247.0 8973000. 90.00000
X2,Y2,Z2 : 318866.0 8973990. 90.00000

---

The problem is: this new coordinates X1,Y1,Z1 are completely inside the domain, as is the 1D line defined by the two points.

I tried different coordinates; some work and some don't, but I could not find the reason or a forum discussion about it.
I wonder that there is a problem with Coupe Subroutine when checking domain limits.

Please see attached files.

Any insight will be highly appreciated.

Thank you,
