Dear all.
My question is: i need to simulate a flow through a regenerator. Inlet boundary condition is periodic, imposed by
#include "udf.h"
#include "metric.h"
#include "mem.h"

DEFINE_PROFILE(vs,t,i)
{
face_t f;
real ti=CURRENT_TIME;
begin_f_loop(f,t)
{
F_PROFILE(f,t,i)=1.6*sin(33.33*M_PI*ti);
}
end_f_loop(f,t)
}

But in the results, for time=0.015 the velocity in the inlet is 2.57 and not 1.6 like it must to be.
Inlet velocity is biger that my imposed velocity.
What it can be? Is some thing is wrong?
Please, help me, Im desperate.
