It allows you to enter additional nodal mass and nodal mass moment of inertia values.  Each nodal mass or mass moment of inertia includes the node ID, the mass direction, and magnitude.  The mass direction is specified in the global coordinate system.  The unit of measurement for mass is force divided by the acceleration of gravity.  For mass moment of inertia, the unit of measurement is mass times length units squared.  The acceleration of gravity is generally takes as a constant value of 386.09 in/sec^2 or 9.8 m/sec^2.
