3.2.1.1. Plain Constraint Handler

This command is used to construct a Plain constraint handler. A plain constraint handler can only enforce homogeneous single point constraints (fix command) and multi-point constraints constructed where the constraint matrix is equal to the identity (equalDOF command). The following is the command to construct a plain constraint handler:

constraints Plain

This constraint handler can only enforce homogeneous single point constraints (fix command) and multi-pont constraints where the constraint matrix is equal to the identity (equalDOF command).

It does not follow constraints, by that we mean the constrained node in a MP_Constraint cannot be a retained node in another MP_Constraint.

Example

The following example shows how to construct a reverse Cuthill-McKee numberer.
