*SetFieldDamping() - single field
Sets the damping properties of a single field.
Syntax
*SetFieldDamping(field_name, CRATIO|MATRIX, cratio|c1-c36)Arguments
- field_name
- The variable name of an existing field.
- CRATIO|MATRIX
- Use CRATIO to apply damping as a percentage of stiffness, or use MATRIX to supply a 6x6 damping matrix.
- cratio
- Damping as a percentage of stiffness, applied to each stiffness.
- c1-c36
- Linear damping for each entry of the 6x6 damping matrix.
