Hello,
reading the forum posts I can confirm the observations of Amanj. Last year at the User Club I presented some 2D numerical modelling of dam-break, see the proceedings, p.51, in
www.opentelemac.org/index.php/binaries/s...nce-2014-proceedings
So at that time I was curious and tried to simulate the case with Telemac-3D & Sisyphe.
However I had no chance to get stable simulations. I varied some suspect Telemac-3D keywords which could be the reason for the instabilities but after a while I gave it up. But, maybe I just didn't find the right keyword? I'm not that expert in Telemac-3D.
Actually the Telemac-2D inc. Sisyphe case can be downloaded here:
www.opentelemac.org/index.php/kunena/16-...d?limitstart=0#14295
I consider it as exciting to simulate 3D RANS and sediment transport of a dam-break, so I want to propose a deal:
if someone can port the case to Telemac-3D and run a stable AND water depth oscillating-free simulation, I will spend a good bottle of wine (presumably from Northern Italy) at the next user club
Best regards,
Clemens
