Summary0004081: sixDoF Constrain 'plane' depends on magnitude of normal vector
DescriptionWhen performing a 6 DoE simulation with the plane sixDoFRigidBodyMotionConstraint, the motion of the body does not get correctly constrained if the magnitude of the plane normal is unequal to 1.
Steps To ReproduceRun the Allrun script in the case provided:

A falling sphere with gravity acting in negative x-direction and the surrounding flow in positive x-direction. Due to the plane constraint with normal vector in x-direction, the sphere should not fall. However, if the normal vector is (2 0 0), the shpere will still fall. Only if it is set to (1 0 0), the sphere motion is constrained correctly.
Additional InformationA simple normalization of the normal vector should suffice to resolve this issue.

We could undertake this development for you but will need to secure funding particularly given that the sixDoFRigidBodyMotion is deprecated and superseded by the more general and flexible multi-body rigidBodyMotion system.
