Neodynamics Models Help Virtual Prototype Simulations Converge to Reality Predicting dynamic behavior is a critical task in the development of many new engineered products. Increasingly, engineers are relying on 'virtual prototype' computer models to expedite much of this work. Virtual prototypes predict dynamic behavior mathematically, by combining design parameters (geometry & physical properties) with equations to represent physical phenomena. These models give fast, accurate results, for a wide variety of engineering systems. However, these models can easily misrepresent critical behaviors, when the system under study includes elastomers (rubber), biological tissue, unsteady or turbulent fluids, or other complexities. These systems are often difficult to characterize mathematically. Alternatively, the math may be tractable, but extremely slow. In either case, these types of systems become a bottleneck in the virtual prototyping process. Many of these obstacles can now be circumvented, through the use of Neodynamics™ advanced nonlinear dynamic blackbox models, from Neosimulation Engineering. Neodynamics models are fast, high accuracy models of complex physical systems. They're constructed by combining measured input and output signals (from physical lab tests, or from 'virtual' tests) with the pattern-recognition power of neural networks. Neodynamics models excel at predicting nonlinear, history-dependent behavior. This makes them especially appropriate for modeling biomechanical systems (natural or engineered tissues, polymeric implants, bio-fluid flows), vehicle suspension components (shock absorbers, elastomeric bushings, tires), and other complex systems. Neodynamics models are compatible with Simulink® modeling tools, from The Mathworks. Simulink allows engineers to simulate complex system behavior using a block diagram representation of system components and their interactions. Neodynamics models are packaged as Simulink blocks, which drop seamlessly into Simulink block diagrams. By supplanting less accurate models of complex nonlinear components, Neodynamics models help the Simulink simulation 'converge to reality'. Simulink-compatible Neodynamics models include several special features and benefits:
