KR142: How do I use 6DOF Solver for restricted DOF problems?

You can do limited DOF problems using 6dof solver. You need to set the translational and rotational velocities calculated by the 6dof solver to zero. In Fluent 12, there is a new feature to set each component of the translational or rotational velocity computed by the 6DOF solver to zero.

For example, if you want to restrict the translational motion in X direction and rotational motion in Z direction, then in the 6DOF properties UDF you can specify the components you want to set to zero as following:
