  Hi all,
  I've designed a drone with propellers and I'm simulating it in fluent.
  Entire model is tilted at 30deg.
  What should be the rotational axis direction inorder to spin propellers in fluent

  It'll be a function of +y and -x to suit the 30 degree tilt. We use the right hand rule to then determine whether the rotation speed is + or -

  Hello The easiest way to move forward would be to reorient the mesh by rotating it by 30 degs so that your axis of rotation points along the y-axis. You can then use (0, 1, 0) if you wish an anti-clockwise rotation in the XZ plane.
