Global Damping
The Global Damping PropertyManager sets the options for constructing the global damping matrix.
Compute from material damping. When this flag is checked, the modal damping ratios are calculated based on the material damping ratio MDAMP.
Material damping ratio MDAMP is defined in the Properties tab of the Material dialog box.
Damping Ratios: You specify a critical damping ratio for each mode.
C = a[M] + b[K]: where C is the damping matrix, M is the mass matrix, and K is the stiffness matrix.
Parameters
You can also define concentrated dampers between two locations (for modal time history analysis only).
