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
