open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello all,

i have set up a case of TELEMAC-3D and GAIA. The hydrodynamic part does work fine as long as not coupled to GAIA. Once coupled the simulation crashes with following error message:

Program received signal SIGFPE: Floating-point exception - erroneous arithmetic operation.

C:\...\t3d.cas_2025-04-14-11h34min29s\out_telemac3d.exe ended prematurely and may have crashed. exit code 3

The case is built upon the GAIA example 'Tidal_flats-t3d'.

Thanks a lot and regards!
