Hi, I am using Execute_at_end macro of fluent to print torque values in console window for unsteady simulation of wind turbine.
Here is the udf code I am using
#include"udf.h"
DEFINE_EXECUTE_AT_END(torque_time)
{
Domain *d;
Thread *t;
face_t f;
real NV_VEC(A);
real NV_VEC(force);
real NV_VEC(torque);
real x[ND_ND];
real NV_VEC(radius);
real NV_VEC(torque_final);
real tor;
NV_S(force,= ,0.0);
NV_S(torque_final,= ,0.0);
NV_S(torque,= ,0.0);
d = Get_Domain(9);
begin_f_loop(f,t)
{
F_AREA(A,f,t);
F_CENTROID(x,f,t);
NV_S(force,= , F_AREA(A,f,t), * , F_P(f,t));
NV_D(radius,= ,x[0],x[1],x[2]);
NV_CROSS(torque,radius,force);
NV_VV(torque_final,= ,torque_final,+, torque);
tor= NV_MAG(torque_final);
}
end_f_loop(f,t)
printf("Value of torque at the blades is = %f", tor );
}
My zone is blade and its integer id is 9. I want to print torque values for blade zone only. The issue is its a face thread and I dont know how to pass on that particular thread pointer.
This code is printing anything in console window.
Any suggestions?
