The PBUSH dialog has two sections, one labeled Nominal Values (PBUSH) and one labeled Dependent Properties (PBUSHT)
Each of these tabs has 4 groups: Stiffness, Structural Damping, Viscous Damping on both; Recovery Coefficient on Nominal and Nonlinear on Dependent.
Click on the Dependent Properties. Expand the appropriate damping group. Each entry has a drop down containing the following options:
To create a new table field, pick the Table constructor option. You will see that the independent domain is always frequency.
Structural damping is a ratio, so the dependent domain is always Unitless
Viscous damping dependent domain is Viscoud Damping for translational dof and Angular Momentum for rotational DOF
I was trying to create the field 1st to select it.
Having played with the field table creation, I found that by clicking 'Remove complex domain filter' I can actually create a viscous damping table which can then be selected for the PBUSHT
How do you remove/de-select the field once applied!
