Particle Injection File or DEFINE_DPM_INJECTION_IN
 
I would like to inject particles and to continuously change the location of particular injecting particles as Fluent iterates.

I have tried creating a INJ file that defines the particle characteristics. However, Fluent does not recognize changes to the file as it iterates. You must reload the file for Fluent to recognize it.

I have also tried creating a UDF: #include "udf.h" #include "dpm.h" DEFINE_DPM_INJECTION_INIT(init_inj,plat) {

Particle *p;

loop(p,plat->p)

{

P_INIT_DIAM(p) = 0.000005;

} }

None of these methods appear to change the injection as Fluent iterates. I was wondering if someone could assist me in this problem.
