open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi José,

Ok, thanks for this information. Unfortunately I do not have time to make tests on your case, sorry.

I just remembered that you had chosen the matrix storage 1 in your cas file, and I think it's better to leave the default value, which is 3.

Best regards,
Agnès

Okay, thank very much for all your help.
I will keep working and reading more about it. I will let you know when I improve it.

Wish you all the best!

Cordially,

José

Hello again, Agnès and everyone else.

Finally I have applied all the tips you suggested and actually the result improve a little bit (both KE and Mixing length show similar results). Now I have these kind of null points in the bottom...

Has anyone know why is it happening? I know that probably because my bottom seems to be zero velocity for all profiles... what keyword should I change to turn into a more smooth bottom in order to keep it vertically uniform?

See the attached figures and my case file. I would appreciate your thoughts about it.

Thanks in advance,


Best wishes,









Jose

UP.
Please, no one could help with that?
I just would like to know which keyword define my bottom velocities as zero...I'd like to let it nonzero with a logarithm vertical profile. Ive defined it as 2 in the keyword VELOCITY VERTICAL PROFILES, but it remains starting in zero.

I also turned on Vertical Velocity Derivatives, as well as Bottom Regime, but nothing changed. Here is my case file, in case someone could help me.



Thanks in advance,

José
