Hi everyone !
I was writing a code for a transient temperature analysis, for 0 to 5700 secs i have a equation and for 5701 to 14400 i have another equation for temperature change with time. I wrote the following code #include "udf.h" DEFINE_PROFILE(unsteady_temperature, thread, position) { face_t f; int time; real t= CURRENT_TIME; begin_f_loop(f, thread); { if(t<=5700) F_PROFILE(f, thread, position) = (6*10^(-8))*t^(5)-(7*10^(-14))*(t^(4))+(2*10^(-10))*(t^(3))-(0.0072*t)+326.75; else if(5701<=t<=14400) F_PROFILE(f, thread, position) = -(5*10^(-21))*(t^(5))+(2*10^(-16))*(t^(4))-(5*10^(-12))*(t^(3))+(4*10^(-8))*(t^(2))-0.0002^(t)+306.58; } end_f_loop(f, thread); } Also my doubt is do i have to include some kind of a loop statement for updating time after each iteration ? |
