OD_l: The outer diameter of the cross section of the left beam.; Data type: real
ID_l: The inner diameter of the cross section of the left beam.; Data type: real
CRATIO: This argument indicates the structural damping matirx is a ratio of the stiffness matrix.
ratio_l: Ratio for calculating the damping ratio for the left beam.; Data type: real
len_r: len_r specifies the undeformed length of the right beam.; Data type: real
AUTO_LENGTH: AUTO_LENGTH indicates that the undeformed length of the right beam is calculated automatically using the end points of the beam.
