TOPIC: Time step and CFL Finite Volume implementation of Saint Venant

Time step and CFL Finite Volume implementation of Saint Venant 5 years 6 months ago #33602

Hi,

I'm trying to run TELEMAC 2D with Saint-Venant Finite Volume implementation. I'm getting an error that "Fixed time-step and CFL not given". In the simulation parameters I'm defining Tim-step and Number of time-steps. It works for Finite Element implementation but not for Finite volume. The screenshot along with simulation files are attached for reference. Any help in this would be great. Many thanks in advance.

Just uncomment lines:
Desired CFL number=0.9
And add thé following Lines
Finite volume scheme= 5
Variable Time step= yes

Kind regards
