loop over all injection streams
 
Hi every body
I want to calculate the effect of all particles of an injection on each particle via UDF as DPM_BODY_FORCE. For this aim it is needed to search all over particles at every iterations. I have used following functions to do such a search:
cell_t c;
Thread *t;
Domain *d;
Particle *pi;

thread_loop_c(t,d) /*loops over all cell threads in domain*/
{
begin_c_loop(c,t) /* loops over cells in a cell thread */
{
begin_particle_cell_loop(pi,c,t)
{

But this method is so time consuming because the number of cells in our case's domain is so much. Instead the number of injection streams is fewer in this problem. I have tried to use some functions such as:
Injection *Ilist = Get_dpm_injections();
Injection *I;
loop(I, Ilist)
{

loop(pi,I)
{


In order to loop all over injection streams. But unfortunately these functions don't work in DPM_BODY_FORCE in my case that is in windows7 platform. Are there any other functions that can be used for this aim? Any suggestion will be appreciated.
Regards

You'll get a better response if you post to the sub-forum for the particular software you are using. In this case it sounds like Fluent.
