Hello,

Why do you have a '5' in the column 8 ?

4 4 5 0.0 0.0 0.0 0.0 5 0.0 5 0.0

Why do you have 4 4 5 as BC for hydrodynamics ?

Please also try the following for the inflow/outflow boundaries:
4 5 5 0.000 0.000 0.000 0.000 5 0.000 0.000 0.000
...
5 4 4 0.000 0.000 0.000 0.000 4 0.000 0.000 0.000

To check: Does your hydrodynamics (only, without morphodynamics/sediment transport) calculation give good results. Please check before moving.

Cheers,

Pablo

I'm mean, column 10...

Dear Pablo,

Considering what HKSCHREI wants to do,
Is possible to set no evolution at outflow boundary? whether possible or not, Is that correct (in the manual is indicated as not required)?

cheers,

José

Hi,
The 5 in column 10 was one of the things fudaa seemed to be changing in my file, I don't know why it's there. The rest was taken from the sisyphe manual I found here: opentelemac.com/downloads/MANUALS/SISYPH...r_manual_en_v6p3.pdf
I managed to fix some of my problems by changing the hydrodynamic boundary conditions, but it is still not behaving like a zero evolution boundary. Is it possible to impose that condition on the downstream boundary?
Thanks

Hi,

I am not hundred percent sure, but does not look correct to impose no evolution at downstream, so, i would answer it is not possible.

Also, the manual says at Outflow boundary conditions 'bedload does not require any particular condition' (which makes sense for me). The manual i am using is the last one released (v7.2).

Hope it helps,

Cheers,

José
