*SetFieldDamping() - asymmetric field pair

Sets the damping properties of an asymmetric field pair.

Syntax

*SetFieldDamping(field_name, , CRATIO|MATRIX, cratio_l|c1_l-c36_l, 
                                         CRATIO|MATRIX, cratio_r|c1_r-c36_r)

Arguments

field_name
The variable name of an existing field pair.
Data type: varname
CRATIO|MATRIX
Use CRATIO to apply damping as a percentage of stiffness, or use MATRIX to supply a 6x6 damping matrix.
Data type: real
cratio_l cratio_r
Damping as a percentage of stiffness, applied to each stiffness.
Data type: real
c1_l-c36_l c1_r-c36_r
Linear damping for each entry of the 6x6 damping matrix.
Data type: real

Context

*BeginMdl()

*DefineAnalysis()

*DefineSystem()

Comments

The second argument (used to specify symmetry) is left empty when specifying asymmetric properties for a field pair.
