BOUNDARY_PROFILE UDF

Sandilya Garimella

hello

I am writing a UDF to define the inlet bC for compressible flow

The pressure is defined by

p = P_static + 0.5 * density * velocity *velocity

This I am defining in UDF as given below

DEFINE_PROFILE(press,t,i)

{

face_t f; cell_t c0;

double press; double dens; double vel;

double time=CURRENT_TIME;

begin_f_loop(f,t)

{

/*c0 = F_C0(f,t);*/

press = F_P(f,t);

dens = F_R(f,t);

vel = F_U(f,t);

if(time<20e-3)

{

F_PROFILE(f,t,i) = 101325 + 0.5 * dens * vel * vel;

}

else

{

F_PROFILE(f,t,i) = 0;

}

}

end_f_loop(f,t)

}

But when I hook the UDF in fluent

I get the following error

ACCESS VIOLATION

Can anyone let me know what is the problem?

Thank you
