NX Design Simulation enables design engineersto understand, evaluate and optimize thestructural, thermal and vibration behavior ofparts and assemblies. NX Design Simulationincludes the integrated NX Nastran finiteelement solver for quick-turnaround linearstructural and thermal evaluations as well assizing and parametric shape optimization.

Engineers can quickly perform multiple “what-if” simulations of a product’s structural andthermal performance to choose the mostpromising and innovative conceptual design alternatives. Geometry-based parametric modeling andautomated optimization tools lead to a detailed understanding of a product’s performancecharacteristics and definition of an “optimal” digital design prototype earlier in the productdevelopment process.

NX Design Simulation has been specifically developed to allow users to quickly predict and optimizethe simulated engineering responses of various design alternatives. A complete set of geometry basedanalysis tools is provided.

Also integrated into NX Design Simulation are automated sizing and parametric shape optimizationand fault tolerant adaptive meshing technologies. Using the embedded optimization engine, NXDesign Simulation is able to automatically predict the best geometric and mechanical parameters fora component or assembly based on engineering performance simulation results. Optimization goals,engineering constraints and model variables are defined by the user through a simple process guidedby NX. Direct optimization and sensitivity studies then provide the maximum amount of guidance forthe engineer while fault-tolerant meshing provides a quantitative degree of confidence. Key ease-of-use features in NX Design Simulation include a simulation navigator that guides new users andincreases the efficiency of the more experienced by providing a visual reference to the analysisobjects created in the model. Intelligent meshing algorithms incorporate industry best practices andapply knowledge based approaches to successfully mesh complex geometry, reducing element countwhile increasing element quality. Built-in ‘wizards’ enable vibration and/or stress analyses.

SummaryNX® software delivers design-integrated structural simulation tools that help engineers compare design alternatives and optimizeperformance characteristics of products from the earliest stages of the design process. Complementing and scalable to the NXAdvanced Simulation applications suite, these tools are tightly linked with NX 3D design geometry to accelerate simulation modeling,analysis and results evaluation, so that functional performance simulation results can directly influence design. The result is a a highlyiterative and predictive engineering process that delivers innovative designs, higher quality products and reduced time-to-market.

Supported solution types include linear statics, normal modes, linear bucking, linear contact, steady-state heat transfer and combined thermo-structural; temperature dependent materials are alsosupported. In many cases, engineers are not just focused on if a product will fail. Integrated durabilityanalysis enables design engineers to predict when it will fail. Results of a durability analysis are displayedas contour plots that show the duration of cyclic loading (number of fatigue duty cycles) the structurecan undergo before crack initiation begins. A library containing standard fatigue material properties isprovided. Simple and easy to use!

Validation requires full and complete documentation, a natural process with NX Design Simulation.Report content is controlled and maintained through fully customizable templates ensuring consistencyand quality. While much report content can be created automatically, much more can be added “on thefly,” providing the vital flexibility needed to ensure that reports add value to your business supportingcollaboration, archival and regulation requirements.
