Oasys.PRIMER Damping dictionary

The Damping class allows you to create, modify, edit and manipulate damping cards. Unlike other classes there is no constructor and there are no functions. Instead a Damping object is available as the damping property of a Model object. This object allows you to access the damping cards.
For example,
To activate damping card *DAMPING_GLOBAL in model m and set valdmp to 0.001

m.damping["global"].exists = True
m.damping["global"].valdmp = 0.001

To activate damping card *DAMPING_MODAL in model m and set prflg to 1

m.damping["modal"].exists = True
m.damping["modal"].prflg = 1

To activate damping card *DAMPING_STRUCTURAL in model m and set g to 0.02

m.damping["structural"].exists = True
m.damping["structural"].g = 0.02
