Jessica Guest Posts: n/a	I am starting to write an LES code of mine. I am using the finite volume, staggered grid arrangement, SIMPLE algorithm for solution of the Navier-Stokes Equations. Unfortunately, I dont understand where (in the algorithm) I shall be filtering my primary variables, to calculate the SGS. 1. Anyone have any practical insights on developing a Smagorinsky type LES code? 1b. How does the filter type come into consideration? 2. Anyone ever built his/her own dynamic model (Germano) -- how did you implement the test filter?
