Description

POSTEXT

<YES, NO>

Default = NO

If YES, the modal complex stiffness matrix (KHH) and, if it exists, the modal viscous damping matrix (BHH) are written to the .op2 file when frequency response analysis is performed.

The modal complex stiffness matrix is:

param_postext_1

Where, G is the PARAM,G structural damping value and [Kge] is the structural damping matrix based on the structural damping values on the MATi data.

The modal viscous damping matrix is:

param_postext_2
