Hello!

I am very new to ANSYS. I am modeling a simple conduction + convection model. Although the heat source in this is more like a PULSE. In a 300 msec cycle, a heat pulse of 10 msec long is sent at 50th msec. All the time except for the pulse duration is for cooling.

I have written an UDF, that can be seen below (with my negligible knowledge of writing an UDF). When I try to interpret it, I am getting an errors: 1. line 35arse error, 2. f_loop_last: undeclared variable. I am not able to understand the cause of these errors. I tried looking at other threads, but I still couldn't understand what's wrong.

Can some one please have a look and give me some kind of feedback?

I highly appreciate your time, thank you very much.


Code:

# include "udf.h"
# include "unsteady.h"

DEFINE_EXECUTE_AT_END (execute_loop)
{
face_t f;
Thread *t;
real c_time=0.0000;
real q;
c_time=CURRENT_TIME;

if (c_time<0.05)
{
q=0;
}

if ((c_time>=0.05)&&(c_time<=0.06))
{
q=10000;
}

if (c_time>0.06)
{
q=0;
}

DEFINE_PROFILE(HeatPulse, t, i)
{
begin_f_loop (f,t)
F_PROFILE(f,t,i) = q;
end_f_loop(f,t)
}
}
