Constraints are defined on the analysis degrees of freedom between regions of a model. The following sections discuss the constraints available in Abaqus for CATIA V5:

Creating Rigid Body Constraints: Constrains the motion of regions of a part so that the relative positions of points in the region remain constant throughout the analysis, prohibiting deformation.

Creating Rigid Couplings: Constrains selected degrees of freedom of a region of a part by coupling the motion of the region to the rigid body motion of a handler point.

Creating Smooth Couplings: Constrains selected degrees of freedom of a region of a part by coupling the motion of the region to the translation and rotation of a handler point.

Creating Analytical Rigid Surfaces: Represents a rigid surface in a contact analysis.
