Data errors
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.
