impose temperature udf
 
Hi,

I want to impose a different temperature a different time, i want to impose 700K between t=0 and t=10s and T=400 K between t=10s and t=50s, can you see this udf and suggest me a correction, please?

Code:

#include "udf.h"
DEFINE_PROFILE(inlet_temperature,t,i)

{
real x[ND_ND];
real r;
face_t f;
real dt=CURRENT_TIME;
begin_f_loop(f,t)
{
F_CENTROID(x,f,t);

if ( dt <= 10)
F_PROFILE(f,t,i) =700;
}

if (10 < dt <= 50)

    F_PROFILE(f,t,i) =400;
end_f_loop(f,t)
}
