*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.
 - CRATIO|MATRIX
 - Use CRATIO to apply damping as a percentage of stiffness, or use MATRIX to supply a 6x6 damping matrix.
 - cratio_l cratio_r
 - Damping as a percentage of stiffness, applied to each stiffness.
 - c1_l-c36_l c1_r-c36_r
 - Linear damping for each entry of the 6x6 damping matrix.

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