Hi~

I want to get the average temperature of droplets in an interior in flow zone.
I use DEFINE_DPM_BC macro to get the temperature of each droplets and end the status with PATH_ABORT.
my question is how can I add all the droplets temperature together?
tks alot~

Add two global variables (for example "temperaturesum" and "particlecount"), which you initialize both at one.
Just before you return PATH_ABORT, say

temperaturesum+=particle->temperature;
particlecount++;
Message("Average temperature until now: %f.\n",temperaturesum/particlecount);

The way to access the particle temperature is probably different than what I wrote here, but I hope you get the basic idea.

Tks for your response~
I have tried this method~it works~
but there‘s another problem
the temsum and count are still adding with the fluent iterations
how can I reset the global variables to zero before every step？
