Hi ;)

When performing the telemac2d-sysiphe simulation, in the downstream edge condition; over time an instability is formed downstream (I attach the image), I am using the noerod.f file to define the depth of erosion, and I am currently running with the Engelund-Hansen formula.
How can I correct this instability?

Thanks.

Hi
you set the water elevation and the velocities at the outflow boundary (5 5 5 in the cli-file). Usually only the water elevation is set (5 4 4).
May be this helps.
Best regards,
Rebekka
