Hi,
Some clue how to set up trough UDF two different subgrid scale viscosities (horizontal and vertical directions)...
I'm modelling mixing process of upper ocean using a LES model so that i'm using a high anisotropic grid and none of the available subgrid scale models is appropriate for that kind of problems.
I already know how to include some customized viscosity model, but not two in different directions.

regards, hope to get some hint...
