ljp New Member Join Date: Apr 2010 Posts: 15 Rep Power: 16	HI all, In modeling particle spraying, I try to change some of the particle's properties during flight when certain conditions are met. I wrote a udf using DEFINE_DPM_PROPERTY as in the example shown in the udf manual, but then found out that in the dialogue box for setting particle material, only a few properties allow udf (i.e. have the "user-defined function" option in the drop-down list), and others (like the thermal conductivity) do not have this option. So if I need to change the particle's thermal conductivity, what should I do? thanks in advance! ljp
