i have some problem about definition of particle diameter in mutiphase modeling, i hope that particle has many different diameters, so i want to know how to programme the UDF code.

Thank you for your help!! Have a nice day!!

hi, are you using DPM? if your particle size distribution fits the Rosin-Rammlar equation, you can use the R-R distributin that fluent provides.
