The surface-based coupling constraint in Abaqus provides coupling between a reference node and a group of nodes referred to as the “coupling nodes.” This option provides the same functionality as the kinematic coupling constraint and the distributing

In Step 2 a concentrated load of magnitude 5.0 is applied to degree of freedom 3 of node 1. If node 1 is in node set NLEFT, the total load applied in Step 2 at this node is 15.0: the loads add. The two distributed loads of type P1 acting on element set E1

The respective windows for setting up the coupling constraint in Abaqus, are shown in Figure 1 below. Figure 1: Windows in Abaqus CAE for setting up kinematic/distributing coupling constraints. What needs to be specified for a coupling constraint, is the
