Default UDF for space-filtering 3-D velocity fields

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.
