particle velocity gradient in DPM
 

Hello, everyone

I need to access particle velocity gradient component

dX-velocity/dx

dY-velocity/dy

dZ-velocity/dz

in my udf. These values can be calculated in 'particle tracks'panel, but I can't find macros defined by fluent. Can you help me to get these values in my udf?

This is really a great help to me. Thank you in advance!

Best regards
