UDF for space-filtering 3-D velocity fields -- CFD Online Discussion Forums

April 11, 2008, 21:58	UDF for space-filtering 3-D velocity fields	#1
Xianmin Guest Posts: n/a	Hi, I'm trying to simulate fluid turbulence using LES, need to space-filtering flow velocitity fields for building up a SGS model. For each cell and time step, the filtering should be done by volumetric averaging velocity field over the neighboring cells. I think a UDF should works, but have limited experience on it. Any idea/suggestions? Thanks in advance. Xianmin
