Help! injection loop has no effect

Weijia Qian · March 4, 2016, 09:38

Hi! i hope somebody could help me.
i want to loop between injections and modify them. but it seems that the loop has no effect.
the udf listed below can be built, loaded and hooked. there are two injections but the results show only one.

#include "udf.h"

DEFINE_ADJUST(particle,d)
{

Injection *Ilist;
Injection *I;
Ilist=Get_dpm_injections();
loop(I,Ilist)
{
Message("Initializing Injection qwj: %s\n",I->name);
}

}

why the "loop" has no effect?

Are you sure you have two injections shown in the injection list? If you're using unsteady tracking, also check that your particles are injected at the current simulation time.

Think you very much! But i have to say sorry.
I think UDF cannot create a particle when need in the solving process. therefore, i have to give up the Fluent approach and turn to OpenFOAM.
