open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi all,

The inflow hydro graph is as given below (hydrographs_baxter.liq )

#Open boundary file created for T2D simulation;
#Baxter tutorial inflow hydrographs
#
T Q(1) Q(2)
s m3/s m3/s
0 566.3369318 11.32673864
7200 566.3369318 11.32673864
39000 3567.922671 102.6485689
70800 566.3369318 11.32673864
76200 566.3369318 11.32673864
99999 566.3369318 11.32673864

When i run the telemac2d model i get error as in the attachment.

if i change the hydro graph as given below the model is running.

====================================================

My question is why is it required to specify the third Q value. I assume that it will be taken from rating curve which is specified at the downstream condition. Is this the correct way of running the model ????


Could you please clarify this doubt. Thanks in advance.

Hi
I think it's more in the steering file you should have the 3 values in the keyword: prescribed discharge.
In the liquid file it's not necessary...

Hello

Yes absolutely, as said by Christophe, the number of values must be equal to the number of liquid boundaries. This number is used to allocate some arrays in the initialization step of the computation.

with my kind regards
