January 17, 2022, 19:39	gravitational acceleration	#1
hobing New Member HOJUN YU Join Date: Jul 2020 Posts: 24 Rep Power: 5	Hi all. tihis question is simple. In a top-down flow, if the falling direction is in the +x direction, EX) inlet coordinate (-100,0,0) outlet coordinate (100,0,0) then the gravitational acceleration of x is 9.81? Or is it -9.81 regardless of the coordinate system? help thank you
