System-based Modeling

Designing large, complex products requires the performance and capacity to create and evaluate assemblies comprised of thousands of components. In recent years, the industry has witnessed a trend toward a system-based approach that allows products to be broken down into physically and functionally self-contained subsystems or modules. These subsystems have well-defined interfaces that allow them to "plug and play" with a variety of other subsystems.

NX delivers a system-based modeling solution, termed WAVE, that offers unprecedented control for the development of complex products. System-based modeling enables you to manage product complexity, capture high-level product criteria and rapidly evaluate design alternatives. This system-based approach also supports initiatives like platform engineering.

With NX system-based modeling, GE Aircraft Engines saved 3 to 6 months time in developing a new engine, performed 20 times the analysis iterations in 25% of the time, and realized a 50% savings in manufacturing costs.

Product-level design control

NX fosters a systems-based product engineering approach, with a control structure that communicates design criteria to subsystem developers, including suppliers. This tight control allows distributed design teams to work concurrently within a common product framework.

Designing products from the top down and independent of geometry accelerates the initial stages of product planning using information from prior designs. System-based modeling streamlines the initiation of new products by linking simplified conceptual models to the control structure. Changing product parameters in the control structure and propagating the changes through to the conceptual design allows users to quickly investigate design alternatives.

By subscribing to these criteria, subsystems can be designed to meet the needs of the overall product. Product-wide changes are initiated in the control structure by changing key product parameters such as the wing angle of an airplane or the table size, height and capacity of a machine tool. These changes are automatically propagated to the subsystem designs.

System-based modeling offers a top-down, modular approach to product development and maximizes re-use of subsystem designs across products. It promotes the adoption and perfection of consistent design and manufacturing processes. Along with the overall strength in large assembly modelingand inter-part modeling, NX enables the construction of complex, re-usable product assemblies.
