I set a interior face in the flow field
and I want to get the average temperature of all particles which escape from the interior face.
how can I do that?

I have used the DEFINE_DPM_BC macro and use begin_particle_cell_loop
*
cell_t*c =*P_CELL(p);
Thread**t*=*P_CELL_THREAD(p);
Particle**pi;
begin_particle_cell_loop(pi,c,ct)
{
pt =P_T(pi);
}
end_particle_cell_loop(pi,c,t)

and there is an error: access_violation

tks a lot~

The DEFINE_DPM_BC macro is called whenever a particle impacts the wall this macro has been applied to. Why are you trying to loop through all particles every time a particle passes through this interior face when you're only seeking the single particle temperature?

Are you pointing to pointers of pointers?!

Hi again~
my propose is to get the average droplets temperature through the interior, and the status of droplets is escape.
i don't know how to do, so i tried the DPM_BC macro.
is there any method to calculate the average temperature of all escape droplets directly?
