Simcenter 3D CAE

There are two options – NX CAE or NX Nastran – available for your product analysis requirements. NX™ for Simulation utilises the market leading simulation tool Nastran solver – originally developed by NASA – to bring finite element analysis (FEA) to a designer level. This serves to relieve possible bottlenecks by removing the need to allocate work to analysts and structural engineers, helping save you time.

Take real world scenarios that could impact on your designs and simulate them in a virtual environment. Then easily document results of this validation with fully customisable templates for consistency and quality. Make use of a simulation navigator that assists new users and helps to increase the efficiency of those more experienced. We provide training in the use of Nastran integrated with NX to ensure you’re getting the most from the software.

An Advanced Computer-Aided Engineering Solution

Whether you are an advanced analyst or design engineer, NX CAE integrates best-in-class modelling with simulation solutions into a single environment. These include:

  • Simulation modeling and results visualisation
  • Structural analysis
  • Thermal analysis
  • Flow simulation
  • Motion analysis
  • Multiphysics
  • Engineering optimisation
  • Simulation data management and automation
  • Simulation-driven design

Additional benefits can be realised when used in conjunction with NX CAD, such as seamless data transfer between your design team and analysis team. Although, NX CAE does not require NX CAD and can be used as a standalone pre/postprocessor because of the support for multi-CAD geometry and external CAE solvers.

NX™ Nastran® – Basic is the core subset of NX Nastran software and includes a robust suite of linear statics, normal modes, buckling analyses, heat transfer and basic non-linear capabilities. NX Nastran – Basic can play a key role in your virtual product development process by providing the most widely used CAE solutions for digital prototyping and simulation of product functional performance.

Available as a standalone solver or integrated in NX CAE.

Multiple Solution Domains – One Solver

NX Nastran solves most structural analysis problems for linear and non-linear analysis, dynamics, acoustics, rotor dynamics, aeroelasticity and optimisation. This simplifies your task because input/output file formats are the same for all solution types.

Computational Performance and Numerical Accuracy

Two distinct parallel processing capabilities are offered by NX Nastran; shared memory parallel processing (SMP) and distributed memory processing (DMP). SMP is the preferred technology for either multiprocessor nodes with shared memory or processor nodes with multiple cores. While DMP can provide much higher levels of scalability for major computational challenges such as large system-level static and dynamic analyses.

Ease of Modeling and Engineering Workflow

NX Nastran includes unique features such as simplified component connectivity, superelements to simplify complex FE modeling, automatic dependency conflict resolution, and direct interfaces to multibody dynamics (MBD) solutions.

Advanced Applications

NX Nastran is able to tackle a variety of advanced applications, such as composites analysis in the aerospace industry, NVH (noise, vibration and harshness) problems in the automotive industry, complex coupled thermo-structural problems in electronics, and a number of other industries.

Flexibility and Openness

The option to write your own applications and add add your own custom analysis modules with the direct matrix abstraction program (DMAP) is available to you in NX Nastran. You can also combine third-party solvers for coupled analysis.
