Input Parameters for Shear Kalman Smagorinsky BGK

[anandanandan86]

Hello, I am trying to use the Shear Kalman Smagorinsky BGK model, but I am unsure of one of it’s input parameters. Its constructor requires a parameter called “f_char_lat”. What is this parameter and how can it be calculated?

Hello, which OpenLB release do you use?

[anandanandan86]

Hello, I am using OpenLB 1.4

[FBukreev]

Hello, this model does not work well there and we don’t use it in our next release. Ufortunately I cannot help you with it. A better way for you could be to use the standard Smagorinsky model with some own modification that you implement as a separte functor or you modify the collision in the smagorinsky dynamics.
