SIEMENS Femap with Simcenter Nastran : Nastran for Femap : Interactively supports a broad range of capabilities
Optimization : Designing and producing an innovative product that meets its performance criteria is a goal of every manufacturer. Using optimization techniques, an engineer can improve a proposed design, resulting in the best possible product for minimum cost. Because your designs may have hundreds of variable parameters, with complex inter-relationships, finding an optimal design through manual iterations is hit-or-miss at best. NX Nastran–Optimization software relieves the burden involved in improving product designs by automating the iterative process of comparing your design’s performance against its performance specifications.
Rotor Dynamics : Rotating systems are subject to gyroscopic forces such as Coriolis and centrifugal forces that are not present in stationary systems. NX Nastran® Rotor Dynamics software provides the capability to predict the dynamic behavior of rotating systems. With the Rotor Dynamics functionality now integrated into NX Nastran, users can now more easily simulate rotating system loads, perform synchronous and asynchronous analysis to generate Campbell Diagram data, predict whirl frequencies and critical speeds and detect instability in rotating components.
Superelements : Despite the ever-increasing power of computers, finite element models are continuing to get larger, which means that finite element analysis (FEA) solutions can require hours of compute time. NX Nastran® software solves large systems of equations efficiently using sparse matrix algorithms; however, NX Nastran – Superelements offers still greater efficiency. Superelements, an add-on to NX Nastran – Basic, plays a key role when solving very large and complex finite element models by decomposing larger structures into equivalent sets of smaller substructures called superelements. NX Nastran – Superelements can be used with all NX Nastran analysis capabilities; is particularly efficient in large, full-system analysis such as an entire aircraft, vehicle or ship; and performs incremental and partial assembly solutions.
Advanced Nonlinear : The NX Nastran® Advanced Nonlinear software solution enables you to analyze models with nonlinearity from contacting parts, material nonlinearities and/or geometric nonlinearities (that is, large deformations). An add-on module of NX Nastran – Basic, the Advanced Nonlinear solver is an NX Nastran as Solution 601 for implicit solutions or Solution 701 for explicit solutions.
Aeroelasticity : Aeroelastic analysis is a capability that enables the analysis of structural models in the presence of an airstream. With NX Nastran® – Aeroelasticity, an optional add-on module to NX Nastran – Basic software, you have access to static aeroelastic capabilities for stress, load, aerodynamic and control system analysis and design using a common finite element representation. As such, it is applicable in the design of airplanes, helicopters, missiles, suspension bridges and even tall chimneys and power lines.
Dynamic Response : NXT Nastran® – Dynamic Response software enables you to calculate your product’s forced dynamic response to inputs (loads or motions) that vary with time or frequency. An add-on option to NX Nastran – Basic, it complements the linear static and mode solution capabilities found in the Basic solution. Dynamic response capabilities play a key role in various industries such as assessing passenger comfort in aircraft and automobiles under different operating conditions; determining whether engine frequencies or tire excitations from the road suface will adversely affect responses at other areas of a vehicle, such as at the steering column or in the seats; or evaluating the effect of vibrations on the performance of consumer products and other high-tech electronic devices.

Simcenter Femap : Minimize costly prototyping using best-in-class simulation workflows for analysts
Simcenter Femap is an advanced simulation application for creating, editing, and inspecting finite element models of complex products or systems. You can use advanced workflows in Simcenter Femap to model components, assemblies, or systems, to then determine a model’s behavioral response when subjected to real-world conditions. In addition, Simcenter Femap provides powerful data-driven and graphical results visualization and evaluation, which in combination with the industry-leading Simcenter Nastran, delivers a comprehensive 
Composites : In the quest to make products lighter yet stronger, manufacturers are increasing their use of composite materials. Simcenter is at the leading edge of composites analysis through continuous development of material models and element types. Simcenter speeds the entire process for simulating laminate composite materials through a seamless connection to composites design, accurate solvers and comprehensive post-processing. Computational fluid dynamics (CFD) simulation : Simcenter provides industry leading computational fluid dynamics (CFD) software for fast, accurate CFD simulation of almost any engineering problem that involves the flow of liquids, gases (or a combination of both), together with all of the associated physics. Structural Simulation : Understanding how a component or product assembly reacts under stress or vibration is critical in any industry, but as products and materials become increasingly complex, engineers need tools that go beyond linear statics analyses. Simcenter includes the structural solutions you need for a wide range of structural analysis problems within a single user environment.
Thermal Simulation : Simcenter includes comprehensive, best-in-class thermal simulation capabilities that can help you to understand the thermal characteristics of your product and subsequently tailor your thermal management solution for optimal performance. Meshing : Efficiently mesh your models using extensive modeling functions for automatic and manual mesh generation of 1D, 2D and 3D elements in addition to numerous techniques for the application of loads and boundary conditions. User-defined geometry edits, mesh and boundary conditions are all associated to the base design, which means when the base design geometry changes, you can rapidly update your model. This approach greatly reduces downstream modeling time, which results in huge time savings across a project’s many design-analysis iterations.
Optimization : How can I reduce material in a component or change its properties while ensuring it continues to meet performance targets? Simcenter delivers engineering optimization techniques that can help you answer these this question by systematically searching for the best design that satisfies certain criteria. Reduce component weight or find the right combination of parameters to improve product performance through comprehensive topology, geometry, and parameter optimization capabilities.
Pre / Postprocessing : Reduce the time you spend preparing analysis models, and spend more time evaluating results. Quickly move from multi-CAD geometry data to a complete, run-ready analysis model using unique tools for CAE geometry editing, comprehensive meshing, FE assembly management, multi-CAE solver environments, and fast simulation results post processing and reporting.
Simulation Automation & Scalability : As companies increase their reliance on simulation, they are seeking ways to speed-up the analysis process and increase simulation throughput. One way to increase simulation throughput is to capture repetitive CAE processes, standardize them, and then automate them.
