Dear users,
I know that the maximum number of injected particles from any surface is equal to the total number of mesh points over that surface. I wrote a UDF to increase that which is as followings:


#include "udf.h"
DEFINE_DPM_INJECTION_INIT(init_inject,I)
{
real x;
real ymax;
Particle *p;
ymax=20e-3;
x=rand()* ymax / RAND_MAX ;
P_POS(p)[0]=0;
P_POS(p)[1]=x; 
}

but I recieve a SEGMENTATION VIOLATION error. Please help me to fix it.
