For more information, see Define Response Dynamics result types.

Select Node	Lets you select a node on the model relative to which to evaluate the response.Note: After you evaluate peak response results of displacement, velocity, and acceleration, and when you use an observation node, the observation node is listed in the Information window when you request information on the response results.
Node Label	Lets you select the node by node label.Press Enter or click Select to add your entry.To edit your selection, click Edit Node Selection .
Response Request
Coordinate System	Available for Result Types of Stress and Shell Resultant.Determines the magnitude and direction of vector and tensor data components:Material CS — Generate the response function in the material coordinate system. Choose this option if your analysis includes the material features of the structure (such as a composite material).Element CS — Generate the response function in the element coordinate system. Choose this option if your analysis focuses only on the elements of the structure.Absolute Rectangular — Generate the response function with respect to the global (absolute) coordinate system.Work Rectangular — Generate the response function with respect to the WCS origin.Note: Depending on the coordinate system used in the modal solution, the results may not be displayed in the coordinate system you select here. For more information, see Response function coordinate systems.
Ply Coordinate System	Applies to RMS and LCR results only.Appears when the dynamic solution results file contains ply stress modes. There is only one option, Ply CSYS, which is an indicator that the composite elements in the model are evaluated with respect to the ply result coordinate system.
X, Y, Z, Rx, Ry, RzXX, YY, ZZ, XY, XZ, YZ, VonMises, MaxPrincipal, MinPrincipalNXX, NYY, NXY, MXX, MYY, MXY, QXZ, QYZ	Lets you choose the directions in which to evaluate the response. The data components that appear depend on the Result Type. For more information about these data components, see Vector and tensor components and invariants.For 2D elements, these check boxes let you choose the components of the membrane (NXX, NYY, and NXY), transverse shear (QXZ, QYZ), and bending (MXX, MYY, MXY) stress resultants to plot on the elements. See Shell stress resultants for more information.Note: The shell stress resultant component names that appear in Pre/Post post-processing do not match the component names that appear in the Simcenter Nastran result files. The Pre/Post component names correspond to Simcenter Nastran shell stress resultant component names as follows:Response DynamicsSimcenter NastranNXXFXNYYFYNXYFXYMXXMXMYYMYMXYMXYQXZQXQYZQY	Response Dynamics	Simcenter Nastran	NXX	FX	NYY	FY	NXY	FXY	MXX	MX	MYY	MY	MXY	MXY	QXZ	QX	QYZ	QY

Evaluation Settings
Available on the Evaluate Peak Results dialog box for Response Spectrum events.
Evaluation Method	Select a rule for calculating the response values. The software combines the response of each mode and each excitation according to the rule you select.ABS — Absolute Value rule.SRSS — Square Root of the Sum of the Squares rule.NRL — Naval Research Lab method.CQC — Complete Quadratic Combination rule. To combine responses to multiple excitations using the CQC rule, you can select ABS or SRSS in the Combination Method box.NRC_Double_Sum — Nuclear Regulatory Commission rule, double-sum method. Used for modal models with closely spaced natural frequencies. To combine responses to multiple excitations using the NRC rule, you can select ABS or SRSS in the Combination Method box.Of the evaluation types, ABS, SRSS, and NRL use the same combination rule for multiple excitations. If you choose CQC or NRC_Double_Sum, you must also select either ABS or SRSS in the Combination Method box.For more information about the evaluation methods, see Response spectrum analysis.
NRL Neighboring Factor	Available when Evaluation Method is set to NRL, for Response Spectrum or DDAM events.If you set this value to 1.0, no neighboring modes are used to compute the NRL Method peak modal response. If you set this value to 1.1, and a peak modal response is at 100 Hz, modes in the range of 90.9 to 110 Hz (that is, +/- 10 percent of the peak modal frequency) are included in the peak modal response calculation. The larger the NRL factor, the larger the range from which neighboring modes are selected. The lower the factor, the smaller the range from which neighboring modes are selected.= the natural frequency of the -th mode, which is at the peak response= NRL Neighboring factor, which you define= the natural frequency of the 1-th mode, which is the lower end of the neighboring frequency range= the natural frequency of the 2-th mode, which is the upper end of the neighboring frequency range		= the natural frequency of the -th mode, which is at the peak response		= NRL Neighboring factor, which you define		= the natural frequency of the 1-th mode, which is the lower end of the neighboring frequency range		= the natural frequency of the 2-th mode, which is the upper end of the neighboring frequency range

	= the natural frequency of the 2-th mode, which is the upper end of the neighboring frequency range
Combination Method	Available when Evaluation Method is set to CQC and NRC_Double_Sum, for Response Spectrum events. Lets you combine responses to multiple excitations. Choose either ABS or SRSS.
NRC Double Sum Time Duration	Available when Evaluation Method is set to NRC_Double_Sum, for Response Spectrum events.Enter the duration of the excitation.
Crossing Level
Available on the Evaluate LCR Results dialog box.
Crossing Level	LCR calculates the Level Crossing Rate for random results above a specified response level. The results to check may be selected displacements, stresses, element forces, strains, strain energy, and shell stress resultants, depending on the results that are available. For example, for stress results, enter 300 to check the rate the stresses cross 300 MPa.
Description
Description	A description of the evaluation. This text appears in the Description column in the Simulation Navigator for the results generated by this evaluation. This description is useful for keeping track of several sets of results.
Preview
Data Component	The direction component in which to preview the evaluation.
Beam Element	If you are evaluating stress or strain for beam elements, select the stress recovery point on the beam cross section where you want to recover response results. The letters C, D, E, and F correspond to the four stress recovery points on a typical beam section.
Shell Element Layer	For shell elements, select the region over which the stress and strain should be calculated: Top or Bottom.
Show Result	Displays a preview of the results as a contour plot.
