GroundEffect ( GoundEffectFlag )

Options Card

Arguments GroundEffectFlag 0 — ground effect simulation is OFF
1 — ground effect simulation is ON
Description Switches the ground effect simulation on and off. The ground plane is set at y=0.

Note that during the analysis in ground proximity, a mirror image of the airfoil section is automatically created at y=0. Therefore the airfoil must be moved upwards to avoid intersection with the ground respectively its mirror image.

Remarks Performs the same action as if the ground effect check box was (un)checked.
