Currently the truss element interpolates u,rx for the stiffness; u,v,w,rx for the mass. Should it include the interpolation of ry and rz? This would affect the mass by increasing the effect of the second moment of areas on the mass matrix calculations.

Try to build a verification case that can be compared to Nastran.
