dynLagrangian - IC and BC for flm and fmm
 
Hi all,

I would like to use dynamic Lagrangian.

I don't know how to estimate initial and boundary condition for flm and fmm.

In my study, I have an turbulent inlet, an outlet, a symmetry plane and some walls.

Thanks in advance,

vut

It's my problem too.
can any one help use?

I'm facing the very same problem, so I went through the article of Meneveau :"A Lagrangian dynamic subgrid-scale model of turbulence".
If I'm not wrong during the validation on a fully developed channel flow flm is set to zero at wall whereas fmm to zeroGradient.

Initial conditions are still an open issue for me.

Also encounter with this issue

Hi Formers,


I still have this problems unsolved, do you know how to set them? Thank you!
