Hanz New Member Join Date: Jun 2009 Posts: 14 Rep Power: 17	Dear all, I am experiencing a problem with data errors. I have a cluster of particles injected in from a surface. I want to simply find the relative velocity between the particles in a cell, which I have set up using a UDF. I know that the calculated value I have should be roughly zero, however there seems to be an error of roughly 0.7m/s for all results. I can see this by comparing the velocities of individual particles. Any ideas. Some help would be great. Hanz
