open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I would like to model a stilling basin.
To do this, I try to use the k-e model but Telemac displays an error message :
"les plans se croisent".

If I use a constant viscosity for horizontal turbulence
and mixing length for vertical turbulence, I have not this problem.

So what are the better parameters to use the k-e model ? (schemes for convection, diffusion, solver, solver option)

Thanks for your help.

Hello

these are not the real problem of your model. horizontal planes can inter-cross when you have negative depth or you have bad intitialization.
verify these options before going ahead with K-eps
Otherwise, an easy way to start with the code is to start with one of the validation cases and then modify it in order to adapt it to your case.


with my best regards
