open TELEMAC-MASCARET The mathematically superior suite of solvers

I was trying to use a bigger time step of 400 seconds and aiming to verify the numerical stability, I've used the keyword:

SCHEME ADVECTION FOR VELOCITIES = 5

Then, I got this error in the image. This means an error due to Courant Number > 1?

Thank you all.

Hello,

We cannot see any image. Be careful with the extension you use with the name of the file.

400 s is quite big but it can work if you have local velocities and size of the elements compatible with it (generally very low velocities or nil + quite big size of triangles). Can you give more information about them?

If you got an error, the first advice is to decrease the time step (once or more).
