Optional parameters
- MASS MATRIX INPUT
-
Set this parameter equal to the value of fraction of critical damping for all mass matrices included in the model by using the MATRIX INPUT, MATRIX=MASS option. If this parameter is omitted, the default is zero.
- STIFFNESS MATRIX INPUT
-
Set this parameter equal to the value of fraction of critical damping for all stiffness matrices included in the model by using the MATRIX INPUT, MATRIX=STIFFNESS option. If this parameter is omitted, the default is zero.
Data lines to define a fraction of critical damping
- First line
Element number or element set name.
Fraction of critical damping, , for mass matrices included in this element or element set.
Fraction of critical damping, , for stiffness matrices included in this element or element set.
Repeat this data line as often as necessary to define modal damping for different elements and/or element sets.
