Specifies the absolute displacement of the restraints included in this spectrum shock case for independent support motion analysis (ISM). This displacement is applied to all restrained nodes in the node group and is used to calculate the pseudostatic load components representing the relative displacement of the individual restraint sets. If no value is entered, and if the defined shock for this row does not encompass the entire system, this value is calculated by the software. The value is taken from the lowest frequency entry of the response spectrum: the specified displacement, velocity/frequency (for velocity spectra), or acceleration/frequency2 (for acceleration spectra). Frequency is angular frequency.

This option is only available when Earthquake (spectrum) is selected for Analysis Type.
