求助：UDF传递温度，通过编译但初始化错误

一个圆管中一端流入一端流出，壁面加热，要把出口的平均温度赋给入口
udf如下：
real NV_VEC(A);
real avg_temp;
real sum_T_A=0.0;
real sum_A=0.0;
Thread *thread_out;
face_t f;
Domain *domain;
DEFINE_PROFILE(inlet_T, t, i)
{domain=Get_Domain(2); /2是fluid的id/
thread_out=Lookup_Thread(domain,4);/4是出口面的id/
begin_f_loop(f,thread_out)
{ F_AREA(A,f,thread_out);
sum_A+=NV_MAG(A);
sum_T_A+=NV_MAG(A)*F_T(f, thread_out);
}
end_f_loop(f,thread_out)

avg_temp=sum_T_A/sum_A;

begin_f_loop(f,t)
{
F_PROFILE(f,t,i) = avg_temp;
}
end_f_loop(f,t)
} 初始化后Error:
FLUENT received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.

Answer 1

domain=Get_Domain(1);

In the case of single-phase flows, domain id is 1 and Get Domain(1) will return the fluid
domain pointer.

Answer 2

你好，我也有你这个问题，能不能把你写的最终的udf分享一下
