Hi Bo,

I think suppose if u want to define mass flow inlet with respect to X,Y,Z direction means, no need to go for UDF in boundary condition panel go for direction specification method in that direction vector in next tab co ordinate system select X,Y,Z and define ur flow of mass flow inlet direction.......

With regards, Raghu
