Filtering Prob. for LES
I just set up the three-dimensional NS for cavity flow
these days, I'm modifying the code to LES code. I have no idea where I put the filtering subroutine in my code. the algorithm of code is like this (looks like same as TEACH algorithm) call init l l start time l l call solve for u,v,w,p l l call solve viscosity l l check time and steady condition ----- like this.. I want to use smagorinsky model at viscosity subroutine if I use like this one, where do I put the filter subroutine in? Please give me some ideas |
Re: Filtering Prob. for LES
The finite volume formulation acts as an implicit filter. If you are happy using implicit filter then don't bother with a filtering subroutine as you dont need it. If you use a filter then call it between the velocity solution and the viscosity calculation.
Good luck. Tim. |
