NX Nastran Dynamic Response provides an advanced suite of tools aimed at providing users with a flexible tool to analyze the response of models that are subjected to loads that vary with time or frequency. As such NX Nastran Dynamic Response includes a comprehensive range of response simulation capabilities; normal modes analysis and complex Eigen analysis, frequency and transient response analysis, acoustic analysis, response and shock spectrum analysis, component mode synthesis, and random vibration analysis. In addition Dynamic Response can be effectively coupled with other analysis types such as Superelements, Non-linear analysis, design sensitivity, and optimization. These solution types can be leveraged for a number of advanced simulation capabilities to analyze more complex phenomena such as control systems, coupled fluid/structures, Gyroscopic and Coriolis effects and transfer function. NX Nastran Dynamic Response is a specific add-on module to NX Nastran (NXN001), it is also included in the NX Nastran Advanced Bundle (NXN002). The covered NX Nastran Solution sequences include: 107, 108, 109, 110, 111, 112, 118, and 187.
With the Femap with NX Nastran Optimization module you can improve upon existing designs through the manipulation of element properties such as plate thicknesses and beam sections. The design can therefore be optimized to minimize weight for example, while maintaining specific responses such as displacements or stresses. Optimization may be applied to a broad range of NX Nastran analysis types, such as linear statics, normal modes and buckling analyses. In addition, it also includes a broad range of optimization capabilities that can be used with the more advanced NX Nastran capabilities such as dynamic response.
The Advanced Nonlinear Solver enables users to address a range of challenging nonlinear simulations including surface-to-surface contact, large deformation, large-strain, and nonlinear material properties in accordance with Femap.
Material models that can be used include: elastic isotropic, elastic orthotropic, composites, gasket materials, elastic-plastic, hyperelastic, temperature dependent, nonlinear elastic and elastic creep.
Solution capabilities include: static solutions, dynamic solutions, creep analysis, load displacement control, and automatic time stepping. Surface contact capabilities include: single and double sided, self contact, all contact, friction models, offsets, and rigid and flexible contact surfaces.

NX Nastran Rotor Dynamics is an add-on module to NX Nastran Dynamic Response or NX Nastran Advanced, for performing dynamic response analysis of rotating systems. NX Nastran Rotor Dynamics will enable users to predict the dynamic response of rotating systems such as shafts, turbines, and propellers. The analysis will predict modes of the system as a function of shaft rotational speed and identify the critical speeds of the shaft (i.e. speeds at which the response becomes unstable). Solution capabilities include: multiple rotors, fixed or rotating coordinate frames of reference, general model types (i.e. does not have to be line model), symmetric or unsymmetrical rotor models. In addition, the solver supports synchronous solutions (solve for rotational speed that is coincident with rotor modes) and asynchronous solutions (solve for modes of rotor as function of varying rotor speed).
Structural Analysis Toolkit provides a general purpose result manipulation and processing toolkit for Nastran solutions within the Femap environment. By processing data from a NASTRAN binary results file it is possible to present results in ASCII text, Microsoft Excel, Universal file and HTML formats. This allows easy summation of complex stresses, margins of safety, complex grid point and element forces, modal analysis summaries, random and harmonic base excitations. Valuable analysis time can be saved with the Toolkit through easier manipulation of numerous datablocks and organization of results data.
