Notes
This command defines the stiffness matrix multiplier 
used to form the viscous damping matrix 
, where 
is the stiffness matrix.
Values of 
can also be input as a material property (MP,BETD or
TB,SDAMP,,,,BETD). If BETD in either form is included, the BETD value is
added to the BETAD value as appropriate. (See Material Damping in the Mechanical APDL Material Reference and Damping Matrices in the Mechanical APDL Theory Reference.) Damping is not used in static (ANTYPE,STATIC)
or buckling (ANTYPE,BUCKLE) analyses.
This command is also valid in PREP7.
