open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi everyone
TELEMAC2D report while running :
" PROBLEME MAL POSE, VITESSE LIBRE ENTRANTE"
" PAR EXEMPLE AU POINT DE BORD NUMERO 17262"
I've already cheked the mesh : this node belong to rihgt river banck (outline) which is initialized as (2 2 2) : hard line.

is there any explaination ? any help is welcome

Hello

This means that the flow regime is getting supercritical for this time step.
In that case you need to add a additional condtion (for inlet). For an outlet, this means that the prescribed condition will not be taken into account.

You can reduce your time step or adapt the geometry in the model in order to have smoother bathymetry gradients.

With my kind regards
Riadh

Thank you Riadh,
The nodes where the outlined probleme arise belong to right river banck (hard line). I will se again what I can improve in the DEM and the initial condition and back to you if this probleme back again.

Hi, I would like to know if you resolved this problem. I am getting the same error.

Thank you.

Sorry Jalila I did not, but this is a warning which does not affect the simulation, because it happens at the downstream boundary in my case.
I think also that the initial conditition I've usesed is out from the validity of the Saint Venant equations (constant initial depht everywehre over a complex DEM).
Hope this help
