Specifies the input method for the PSD Load. You have the option to input Frequency vs. G Acceleration data in the tabular view.

Indicates the direction of applied PSD excitation.

Specifies the structural damping used in the analysis. Default setting is 0.02.

Specifies the type of result to be computed. Options are Force Reaction and Moment Reaction.

Determines where the result is computed. Valid input is Boundary Condition, meaning results will be extracted from predefined boundary conditions.

Choose the specific boundary condition applied for result extraction from those available in the drop-down list. Valid boundary conditions are Fixed Support, Displacement and Remote Displacement.

Defines the coordinate system used for interpreting direction-specific results. Only supports Global Coordinate System.

Supports Relative to base motion. This means the response of any location in a structural component is calculated in terms of the relative motion between the base and the structural component, and vice versa.

Defines the direction/component for PSD plot display. For force and moment reaction result types, options are X Axis, Y Axis and Z Axis.
