NX solutions for simulation include NX CAE, which is a modern, multi-discipline CAE environment for advanced analysts, workgroups, and designers who need to deliver high quality performance insights in a timely fashion to drive product decisions.

NX CAE integrates best-in-class analysis modeling with simulation solutions for structural (powered by NX Nastran), thermal, flow, motion, engineering optimization, multiphysics, simulation data management, and simulation driven design into a single environment.

NX Simulation Modeling and Results Visualization

IPreparing a simulation model is a multi-step process of importing and editing CAD geometry, meshing and connecting components, editing material properties, defining boundary and loading conditions, and exporting to the appropriate solver data format. It’s no wonder that up to 80 percent of an analyst’s time can be spent preparing models for simulation.

Structural Analysis

Integrated Structural Analysis Solutions Powered by NX Nastran

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 and dynamics analyses.

NX for Simulation includes solutions for a wide range of structural analysis problems within a single user environment. Engineers no longer need one tool for linear statics, another to study fatigue, and yet another for nonlinear analysis

Thermal and Flow Analysis

Realistic Heat Transfer Simulation

The objective of any thermal management solution is to maintain a product’s temperature within a range that is optimal for performance. The NX CAE suite of solutions 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.

Motion Analysis

Design-Integrated Multibody Dynamics Simulation

Understanding the operating environments for intricate mechanical systems can be challenging. Many CAD tools offer kinematic solutions but they do not provide all the critical information you need, such as the dynamic loads generated by moving parts that can be used to size motors. NX CAE offers multibody dynamics simulation capabilities that go beyond simple kinematics. Motion analysis calculates the reaction forces, torques, velocities, acceleration and more for mechanical systems.

To simulate real-world conditions, analysts must consider the impact of a number of different physics that occur concurrently, such as structural dynamics, heat transfer, fluid flow, nonlinear material behavior and motion. Typically, effects from one physics domain also impact how a product behaves in another physics domain. For example, combined thermal-structural effects are crucial to jet engine engineering. Understanding multiphysics behavior is therefore a major challenge to accurately predicting product performance.
