Hello guys ,
This might be basic question , how can I add a vector product source term .eg F X T , to a momentum equation .
I know it should be some thing like :

#include "udf.h"

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

source = F X T

dS[eqn] = ????;


return source;
}

Both vectors is calculated through another UDS , how can I introduce these vector above and how can I express the mathematical vector product above ?


any suggestion is appreciated
