open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello everyone,

I'm modeling sediment processes in a river. Therefore i use Telemac3d for hydrodynamic and suspended load and Sisyphe for bed load transport. Unfortunately i receives always some errors comparing bottom and bed evolution in the Sisyphe with the Telemac results files. Is this a common problem for coupling those two modules or just in my case?

Another question is that during the simulation in the listing printout the mass balance shows an error (NaN) for the bed-load fluxes at the boundary, see attached figure. Boundary 1 is the Inlet (prescribed discharge) and 3 is the Outlet (prescribed surf. elevation). This means that no bed load enters or leaves the at the boundary, or? Even if there is NaN shown the simulation is ongoing. I attached also my steering files.

Im looking forward to your help,

Best regards,

Markus

Hello,

In the previous versions the evolutions were not well transmitted from one code to the other but this was officially fixed, so I am not sure of what happens. I am also not sure to find someone to look at the problem soon, but at least I could look at the NaN problem if you send me your case.

With best regards,

Hello Jean-Michel,

yes that would be a big help if you find some time to look at my case. The file i to big 2MB, will it be possible to send it directly to you per email? If you can send me an email, i will send the file in return: This email address is being protected from spambots. You need JavaScript enabled to view it.

Already thanks a lot!

Best regards,
