Specifies the number of the starting node in the model at which the displacement is applied.

If the node is a supported node, then the dynamic displacement is assumed to act at the support point. If the node is not supported, then the dynamic displacement is assumed to describe the exact motion of the pipe at that point. This differentiation only becomes important when the node is supported by a flexible restraint. For example, node 55 is supported in the Y direction by a restraint having a stiffness of 5,000 lb./in. A harmonic displacement is also specified at node 55 in the Y direction. In this case, the harmonic displacement does not describe the displacement that is attached to 55. Instead, the displacement creates a load in the Y direction at 55 equal to the harmonic displacement times 5,000 lb./in.

If Start Node has a value but Stop Node and Increment do not, then the start node must exist in the piping system. If all three have values, then the range of nodes identified in the range must include at least one node in the piping system.
