Vector components of force and torque are computed throughout the simulation domain. They are meaningful only on non-air bodies. Selecting this option allows you to view individual vector force components (X, Y, Z) as a contour. The total summed forces and torque are available in the Details view. For example, requesting the z component of directional force/torque will report the net force acting in the z direction and the net torque acting about the z axis of the specified coordinate system.
