WAVE v5.1 builds on the unique capabilities delivered with the WAVE v5 suite and offers additional functionality for modeling transient operation, control, co-simulation and fuel injection. "We're proud to announce the advances and upgrades available to our customers with the release of WAVE v5.1," said Richard Johns, president of Ricardo Software. "We continue to take CAE beyond traditional simulations by continually advancing our software's capabilities and functionality to maintain our leading position in this field." The new features of WAVE v5.1 allow users to: * Perform transient vehicle analysis by using WAVE-generated look-up maps of engine performance. Using a sophisticated sparse data algorithm, the accuracy of the simulation is maximized for minimum calculation effort. Data for the multi-dimensional look-up maps is generated "on-the-fly" and can be re-used in the same and subsequent simulations, thereby maximizing efficiency for long transients and iterative design optimization; * Co-simulate WAVE with mechanical systems using a WAVE-VALDYN interface, providing the ability for fully interactive time-step coupled calculations between detailed engine and valve train models. With this process, the full dynamics of the valve train on the engine and the influence of the engine on the dynamic behavior of the valve train are accounted for properly; * Model 2-phase fuel sprays and wall film evolution for gasoline engine performance by using the Discrete Droplet Model (based on Ricardo's 3D CFD modeling), which accurately simulates phenomena such as cold start and the lags associated with transient operation; and * Efficiently tune PID controllers using a unique built-in gain calibration tool, which completely automates the finding of optimal gains, allowing the engine analyst to start the simulation work with higher confidence while eliminating the routine, low-engineering-value task of finding gains manually. WAVE is the market-leading engine performance simulation software with licenses worldwide in all industry sectors, including motorsport, automotive, motorcycle, truck, agricultural, locomotive, marine and power generation.
