Create a design response that measures the sum of reaction force vectors across a boundary. The response is derived from the solution of a linear static structural finite element analysis.
Operation that will be applied after summing all reaction force vectors over the Boundary input. |X| will compute the magnitude of the reaction force vector projected onto the X-axis, |XY| will compute the magnitude of the reaction force vector projected onto the plane spanned by the X-axis and Y-axis, and |XYZ| will compute the magnitude of the non-projected reaction force vector.
