Okay. Based on the results of our discussion, let me summarize my question:

If I want to continue using non-Newtonian fluids to perform VOF-to-DPM and open secondary breakup, and express the fluid viscosity through UDF, in order to make the program determine the same viscosity definition for both VOF and discrete phase, how do you think the UDF for particle viscosity should be written?
