# Constraints commands

From OpenSeesWiki

Jump to navigationJump to searchIn OpenSees there are two types of constraints:

**Single Point constraints**which prescribe the movement (typically 0) of a single dof at a node. There are a number of commands for defining single-point coonstraints:**Multi-Point constraints**which prescribe that the movement of certain dof at one node are defined by the movement of certain dof at another node. There again are a number of commands for defining multi-point constraints.
