CFD Online Discussion Forums - 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)

}
