如果获取fluent动网格计算中运动表面的时变受力？

"This function needs size of 3 for force and moment. It works in parallel and
the common arguments are the of the same type as your arguments.
In addition you have to pass the domain as first arg and a boolean as
last argument. This boolean has to be TRUE if you also call the function
on the host else it has to be FALSE."
Compute_Force_And_Moment (domain, tf, CG, force, moment, FALSE);
domain = THREAD_DOMAIN (DT_THREAD ((Dynamic_Thread *)dt)); - pointer on Domain
tf = Lookup_Thread(domain, ID); - pointer on the Thread in Domain
I don't know if "force" includes viscose and pressure force or only pressure force!!!
************************************************** **************
compute viscose force in UDF
you have to define in mem.h header or in local c-file this macro:
#define F_VISCOSE(f,tf) F_STORAGE_R_N3V(f,tf,SV_WALL_SHEAR)
Thread *tf = DT_THREAD(dt); /*pointer on thread*/
face_t f; /*number of faces*/
begin_f_loop(f, tf)
{
NV_VS(F_VISC, += , F_VISCOSE(f, tf), *, -1.0 * k); /* compute viscose force vector. k is a factor for depth in 2D computation and -1.0 corrects the sign of viscose force*/
}
end_f_loop(f, tf);

这个函数是difine宏么

Compute_Force_And_Moment(domin, tread, body_centroid, force, moment, TRUE);
试试这个

试了版主的方法，获取的是壁面剪应力，不是我想要的x或y方向的合力，另外我通过monitor-force面板中的设置获得了两个方向力的drag和lift系数，但不知道这两个系数的定义，也没在帮助中找到，请版主指教。

谢谢，

这个不需要使用udf，检测你所需要的力的过程：
