Reduce Your Dependence on Multiple Solution-specific Tools for Each Type of Analysis

Typically, companies use one tool for motion problems, another tool for fluid dynamics, and yet another for structural dynamics. NX offers a single advanced simulation environment that provides solutions for all of these sophisticated analyses, leveraging a common modeling environment, and eliminating the need for external data transfers to link analyses together. In fact, NX includes solutions for all the major causes of failure in electromechanical design, namely temperature, vibration, humidity and dust.

Using integrated NX Nastran and Multi-Physics solvers, as well as design-integrated multi-body motion simulation, NX is capable of solving all your analysis requirements in the following domains:

• Structual
• Thermal
• Flow / CFD
• Response Dynamics
• Multi-physics
• Electronic Systems Cooling
• Optimization
• Multi-body Dynamics
• Motin Control

Structual

NX structural solutions are powered by NX Nastran. For over 30 years, Nastran has been the analysis solution of choice in almost every major industry including aerospace, defense, automotive, shipbuilding, heavy machinery, medical and consumer products for the following types of analyses:

• Linear Analysis
• Advanced Nonlinear Analysis
• Dynamics

Thermal

NX thermal analysis solutions are fully integrated into the NX environment, and are ideal to simulate thermal and heat transfer for complex products and processes within large NX assemblies. NX thermal solutions offer high fidelity simulation of radiative, conductive and convective heat transfer, and can also be used with NX Flow solutions for coupled thermo-fluid simulation.

Basic and advanced thermal solutions capabilities include:

• Thermal and heat transfer simulations
• Radiative, conductive and convective heat transfer
• Advanced radiation effects
• Diurnal environmental solar heating
• Electrical (Joule) heating
• Material phase changes
• Thermal ablation
• Charring and duct flow heat transfer
• Vertical industry solutionsfer

Flow / CFD

NX offers complete computational fluid dynamics (CFD) solutions that are fully integrated into the native NX CAE environment. NX provides sophisticated tools to simulate fluid flow and heat transfer for complex parts and assemblies. The integrated CFD solution allows fast and accurate fluid flow simulations and provides insight into product performance during all design development phases, limiting costly, time consuming prototype testing cycles.

NX Flow/CFD solutions include:

• Internal or external fluid flow including compressible flows
• Non-newtonian fluids
• Particle tracking
• Motion and multiple rotating frames of reference
• Vertical industry solutions

Response Dynamics

Predict dynamic responses of structural systems under various loading conditions. NX Response Simulation produces a broad range of XY plot results and color contour results that aid the user in determining the integrity and suitability of product designs subject to dynamic loads. Analysis information can then be used to perform design studies to enhance the new product development process and ensure the quality of designs prior to physical prototyping and production.

Multi-physics

NX’s heat transfer modeling capabilities can be explicitly combined with the NX’s fluid dynamics (CFD) solutions to allow a user to simulate strong and fully-coupled thermo-fluid interactions problems. Resulting temperature results can also be mapped to a separate Nastran finite element model for coupled thermo-elastic analysis.

Electronic Systems Cooling

NX Electronic System Cooling product is an industry-specific vertical application that leverages the flow and thermal solvers as well as the ECAD data exchange and other high tech and electronics industry-specific cooling capabilities in a bundle product. It provides a comprehensive set of tools to simulate 3D air flow and thermo-fluid behaviour in high tech and electronic systems.

NX Electronic Systems Cooling helps resolve thermal engineering challenges early in the design process and is a valuable aid in understanding the physics of fluid flow and heat transfer for electronic enclosures and cooling applications

Optimization

Optimization is used to refine a part’s design to meet specific design and constraint criteria. NX includes a powerful size and shape optimization engine which designers or engineers can harness directly from within the NX environment. Direct use of NX or imported geometry features as design variables through the power of Synchronous Technology allows for easy modification of optimized results to be incorporated into true design changes.

Multi-body Dynamics

The early use of performance simulation is key to the evaluation of design options. It increases design confidence and reduces risk, thus enabling transformation of the design process. NX CAE provides an advanced yet simple-to-use solution that allows designers and engineers to understand, evaluate and optimize the complex motion behavior of assemblies and products. All geometric models are supported, from simple sketch to complex assemblies, allowing top-down and bottom-up approaches, and it supports models from multiple commercial CAD sources via JT™ or by other direct translation capabilities. Users can rapidly evaluate multiple (and concurrent) design alternatives at all phases during the design process within a consistent NX interface.

Solutions and capabilities include:

• Dynamic, static and kinematics motion simulation
• Joints, springs, dampers, motion drivers, applied forces, contacts and bushings

Motion Control

Companies today face a growing need for mechatronics – i.e., integration of mechanical, electrical and software components as well as systems into a product. Mechatronic simulation can reveal potential problems that may arise when these systems are integrated, allowing multiple iterations on design alternatives and a faster, more efficient development process. NX Motion Control simulation software can be used to perform controller integrated simulations for complete mechatronic machine analysis.

Solution capabilities include:

• Co-simulation with Matlab/Simulink to model interaction of controllers with mechanical devices
• Integrated PMDC motor models with voltage signal input
