Hi

I need help!!!

I'm trying to implement the follow UDF:

DEFINE_ADJUST(adjust_vof_rho_water, domain)
{
Thread *thread_l;
cell_t cell;
face_t face;
domain = Get_Domain(2);
/*Fill UDS whit the variable*/
thread_loop_c(thread_l,domain)
{
begin_c_loop(cell,thread_l)
{
C_UDSI(cell,thread_l,0) = C_VOF(cell,thread_l);
C_UDSI(cell,thread_l,4) = C_R(cell,thread_l);
}
end_c_loop(cell,thread_l)
}
}


DEFINE_ADJUST(adjust_vof_rho_air, domain)
{
Thread *thread_g;
cell_t cell;
face_t face;
domain = Get_Domain(3);
/*Fill UDS whit the variable*/
thread_loop_c(thread_g,domain)
{
begin_c_loop(cell,thread_g)
{
C_UDSI(cell,thread_g,1) = C_VOF(cell,thread_g);
C_UDSI(cell,thread_g,5) = C_R(cell,thread_g);
}
end_c_loop(cell,thread_g)
}
}

DEFINE_ADJUST(adjust_versor_gradient, domain)
{
Thread *thread_l;
cell_t cell;
real n[ND_ND];
domain = Get_Domain(2);
/*Fill UDS whit the variable*/
thread_loop_c(thread_l,domain)
{
begin_c_loop(cell,thread_l)
{
/*C_UDSI(cell,thread_l,0) = C_VOF(cell,thread_l);*/
n[0] = C_UDSI_G(cell,thread_l,0)[0]/NV_MAG(C_UDSI_G(cell,thread_l,0));
n[1] = C_UDSI_G(cell,thread_l,0)[1]/NV_MAG(C_UDSI_G(cell,thread_l,0));
C_UDSI(cell,thread_l,2) = n[0];
C_UDSI(cell,thread_l,3) = n[1];
}
end_c_loop(cell,thread_l)
}
}


DEFINE_SOURCE(x_airdisp_mom_src, cell, thread, dS, eqn)
{
real kappax, rho_lg;
real sigma = 0.073;
real source

kappax = C_UDSI_G(cell,thread,2)[0] + C_UDSI_G(cell,thread,3)[1];

rho_lg = C_UDSI(cell,thread,0)*C_UDSI(cell,thread,4) + C_UDSI(cell,thread,1)*C_UDSI(cell,thread,5);

source = (2*sigma*rho_lg*kappax*C_UDSI_G(cell,thread,0)[0])/(C_UDSI(cell,thread,4) + C_UDSI(cell,thread,5));

dS[eqn] = 0.0;

return source;

}

The PARSE ERROR is in the red line.

I tried defining n[ND_ND] as a global variable, so to difine:

kappax = n[0] + n[1];

but also gave the same error in the expression of kappax.

I also tried adding other UDS in DEFINE_ADJUST(adjust_versor_gradient, domain):

C_UDSI(cell,thread_l,6) = C_UDSI_G(cell,thread_l,2)[0];
C_UDSI(cell,thread_l,7) = C_UDSI_G(cell,thread_l,3)[1];

then,

kappax = C_UDSI(cell,thread,6) + C_UDSI(cell,thread,7);

and also gave the same error in the expression of kappax.

Anyone know what could be the problem????

Thanks!!!

You have the syntax error in the line just above highlighted in red.
