it is just a basic concept.
calculate Vtotal magnitude easily as the following:
Vtotal=(Vx^2+Vy^2+Vz^2)^0.5
then:
x direction= Vx/Vtot
y direction= Vy/Vtot
z direction= Vz/Vtot

direction vector defines the direction of velocity vector entering the domain. for example if inlet flow is along the z-axis, you should easily enter 0,0,1 for x,y,z respectively.
for the output,...

Dear jack;
"reference parameters" are applied to calculate some variables like entropy. for example when calculating delta entropy you need reference pressure and temperature. "reference parameters"...
