hi:who can explain me the following codes;

#include "udf.h" #define CON 20.0

DEFINE_SOURCE(cell_x_source, cell, thread, dS, eqn) { real source;

if (C_T(cell,thread) <= 288.)

{

source = -CON*C_U(cell,thread); dS[eqn] = -CON;

} else

source = dS[eqn] = 0.;

return source; }

what's the mean of"ds"and "eqn"? how to define a "SOURCE"?how many parameters is needed?
