*SetFieldDamping() - symmetric field pair

Sets the damping properties of a symmetric field pair.

Syntax

*SetFieldDamping(field_name, LEFT|RIGHT, CRATIO|MATRIX, cratio|c1-c36)

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
Damping as a percentage of stiffness, applied to each stiffness.
Data type: real
c1-c36
Linear damping for each entry of the 6x6 damping matrix.
Data type: real
