# Displacement Response

Create a Design Response that measures the maximum displacement of some boundary region for a set of boundary conditions. The response is derived from the solution of a linear static structural finite element analysis. The best performance is achieved if: 1) the selected region is local and contains few nodes, and 2) the selected region is loaded or assigned to be passive.
