  Hello everyone ;nIn Natural Convection application : How can i fix the slope of duct for example as (delta h) make difference in calculationnif i want the duct inclined 45 deg or 20 deg ... how can i do this ?nand is there a standard direction in ANSYS ?n

  nIf you have a duct whose length lies along the X axis and cross-section is in the YZ plane, the gravity direction you show is for a horizontal duct.nIf you want a vertical duct, then you just type X = -9.81, Y = 0 and Z = 0.nIf you want a duct with a 30 degree upward slope along the X axis relative to horizontal, then nX = -9.81*sin(30) = -4.905nX = -9.81*cos(30) = -8.496nZ = 0n
