LES subgrid model
As I have said in a previous post, I would like to completely save a profile in a flow to use it as a boundary condition for another flow. Since I am considering LES with Dynamic Kinetic Energy Subgrid-Scale Model, I would like to save speed, and subgrid-scale kinetic energy at each point of the boundary for each time step.
I have seen that, using a velocity inlet boundary type, I can, if I specify the k-epsilon, intensity and length scale, etc... generate perturbations on the velocity profile. But, what if I do not want to perturbate the velocity profile, and instead really inject the subgrid-scale kinetic energy as a boundary condition ?
Re: LES subgrid model
To be more precise, what I need is to find how I can save the Subgrid Kinetic Energy in each cell. I think it might be something similar to C_U for the speed, but I can't find it, neither in the udf documentation nor manually searching the .h files in /opt/Fluent.Inc/fluent6.3.26/src. Once I have saved it, it would be easy to load.
