A consistent mass model will be computed if the INERTIA OF JOINTS CONSISTENT command is given or if rigid body elements are used in the model. The only possible work around at this time is to avoid one or more of these conditions. Other dynamic analysis computations or results are not adversely affected by these conditions.
