regarding UDF
i am using UDF for source term of volumetric heat generation for my 2D simulation of heat transfer. Since i am new user for UDF, so i am in doubt whether i have written a correct UDF or not. UDF is given below.
/* sinusoidal heat generation in heater*/ #include "udf.h" #include "math.h" DEFINE_SOURCE(heat_gen_1e5,cell,thread,dS,eqn) { double source; double time,A,B,omega,pi,time_period ; A = 1.0e2, B=1.0e5; pi= 22.0/7.0; time_period = 900.0; //time in seconds; time = CURRENT_TIME; //taking time value; omega = (2.0*pi)/time_period; source = A+B*(1+sin(omega*time)); //dS[eqn]= B*omega*cos(omega*time); dS[eqn]= 0.0; return source; } Kindly go through this UDF and reply whether it is in correct format or not. Thanking you |
