hello

I am trying to define a velocity profile for the injecting particles at the inlet. I believe that I should use DEFINE_DPM_INJECTION_INIT(name_bubbles,I) macro, however, I get errors while interpreting the file in fluent. the error mentions the stared line in the following code with this message "structure reference not implemented".

I appreciate any help.

DEFINE_DPM_INJECTION_INIT(init_bubbles,I)

{

int i;

Particle *p;

real x;

real x1;

real a;

real um;

real v;

real pos[ND_ND];

a=1.0000e-04;

um=1.9296e-1;

loop(p,I->p)

{

F_CENTROID (pos,f,t);

x= pos[0];

x1=x/a;

TP_INIT_VEL(p)[1] = 2.* um * (1.-pow( x1,2.) );

v=2.* um * (1.-pow( x1,2.) );

}

return v;

}
