Hello,

I have been using the same code for both 2D and Axis-symmetry. while it does not give any error when using with 2D, I get ACCESS_VIOLATION when I use it with Axis symmetry. I have two faces (one solid and the other fluid in the case of axis symmetry since there is a small solid cylinder at the center of the big cylinder). I have tried hooking after few iterations, but it does not work. The code is as given below

DEFINE_ADJUST(adjust_conc,domain)
{
Domain *d;
Thread *t;
cell_t c;

if (! Data_Valid_P())
return;

thread_loop_c (t,domain)
{
begin_c_loop (c,t)
{
if (C_UDSI(c,t,1) < 0)

{C_UDSI(c,t,1) = 0.0;

}
else
{C_UDSI(c,t,1)= C_UDSI(c,t,1);
}

if (C_UDSI(c,t,2) < 0)

{C_UDSI(c,t,2) = 0.0;

}
else
{C_UDSI(c,t,2)=C_UDSI(c,t,2);
}
}
end_c_loop (c,t)
}

}
DEFINE_EXECUTE_AT_END(execute_at_end)
{
Domain *d;
Thread *t;
cell_t c;
d = Get_Domain(1);
thread_loop_c (t,d)
{
begin_c_loop (c,t)
{
C_UDSI(c,t,4)=C_UDSI(c,t,0)+ C_UDSI(c,t,3);
if (C_UDSI(c,t,1) <0.)
{C_UDSI(c,t,1)=0.;}
if (C_UDSI(c,t,2)<0.)
{C_UDSI(c,t,2)=0.;}
}
end_c_loop (c,t)
}
}

Thanx

SM

make sure you use the horizontal x-axis as the axis of symmetry...have you done that?

[swati_mohanty]

Thanx, yes I already have done that. I have now changed the geometry and eliminated the solid face ( I do not deal with heat transfer) and the UDF works fine.
