Penalty

This command is used to construct a Penalty constraint handler, which enforces the constraints using the penalty method. The following is the command to construct a penalty constraint handler:

constraints Penalty $alphaS $alphaM

---

alphaS	penalty \(\alpha_S\) factor on single point constraints
alphaM	penalty \(\alpha_M\) factor on multi-point constraints

---

NOTES:

• The degree to which the constraints are enforced is dependent on the penalty values chosen. Problems can arise if these values are too small (constraint not enforced strongly enough) or too large (problems associated with conditioning of the system of equations).
