open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi, i'm trying to modellate a river in a sector in which the channel is divide in two new streams. I run the program with three boundary conditions. The first one, in the inflow, i use a entering flux of 600 m3/s and in the outflow of both new channels i used a prencribed elevation.
First, i ran the model like a steady state and determined a inicial condition or a hotstart. This initial condition does'nt hasvelocities is just the free surface of water.
Second, i ran the model like a unstady state, with a hidrograph and diferents altitudes.
The results dont have sense. I have velocities Only close to the boundaries and are very small. I though that this was caused for the time of running, but i have tried with 7200 NUMBER OS STEPS and 5 TIME STEP and i continue having no velocities in moust of river.

I attached three documents: The stering FILE "g.cas", the results FILE "f.slf" and the liquid boundaries FILE "CondiFront.liq".

What do you think it could be?,
Thank you very much

Hello

Your steering file is a kind of ratatouille.

As a firts step, you need to abandon it and instead take the stearing file of test case 'confluence' (in folder examples/telemac2d).

Then you have to read carefully the user manual in order to understand the meaning of eack keyword and thus adapt it for your case.

Finally, you run Telemac and hopefully it will give you a physical result.

with my best regards

Hello and thank you riadh!

1) I did my steering file with the help of FUDAA and that its the format.
2) I already done it and i attached it (t2d_A.cas), did not work, neither for the free surface in my river. I also ran the example and it ran without error but when i saw it with BLUEKENUE the flux had not velocities neither.
3) I have already read the two manuals. TELEMAC 2D and SISYPHE. And i understand the meaning of each keyword.
4) However, i have not been able to run correctly the model. I'm new in this, but i have already tried the things that i have learned from the guides, the examples and the Baxter tutorial.

I think that it could be the same thing, because the example did not give me velocities neither.

I also attached my steering file of my initial state (EstadoInicial.cas) and the inputfiles. It works and give me a water surface, but without velocities.

Best regards,
Nicolas
