Hi All, I am new user to fluent. I am doing analysis of a pipe flow which has number of bends, meant flow in bending pipe. it is a 3-D flow. I want to take Gravity effect into consideration. what should be the Sign (positive or negative) of Gravity value in X,Y,Z direction during defining BC. pipe has large no. of bends in 3-D. pls help me. Thank you so much in advance.

Thota is on a distinguished road
If the flow is against the gravity, consider g (-ve)
