i applied folowing UDF to get the inlet profile. but there is deferent in solidwork cfd and Fluent...in fluent velocity goes upward like this..can you give me a solution.
#include "udf.h"

DEFINE_PROFILE(inlet_x_velocity, thread, position)

{

real x[ND_ND];

real z; // Vertical Distance

face_t f;

begin_f_loop(f, thread)

{

F_CENTROID(x,f,thread);

z = x[2];

F_PROFILE(f, thread, position) = 3.5815 *log(z) +30.192;

}

end_f_loop(f, thread)

}


i think problem in my boundary condition not in the code.. please help me
