Ricardo is pleased to announce the release of a new state-of-the-art version of its WAVE engine performance and gas dynamics simulation product. The new features and advanced simulation technologies of WAVE v7 represent a robust virtual development environment offering improved accuracy with solution times reduced by orders of magnitude. Key WAVE v7 features include:

WaveBuild3D: Released with WAVE v7, WaveBuild3D provides a CAD environment which enables users to build solid, three dimensional models which can be automatically meshed for use in WAVE. Based on the powerful ACIS畇olid modeller from Spatial Technologies, this pre-processor enables users to build highly complex geometric models of components such as exhaust and intake systems, concentrating on engineering design issues rather than modelling details.

Run Distribution: This new innovation for WAVE v7 offers the potential to unleash the power of a multiprocessor or network computer system to deliver costeffective, large-scale optimization and massive productivity improvements. Run Distribution licenses enable a single multi-case WAVE model to be broken down into many single-case models and submitted to a network or cluster of computing resources for simultaneous execution. Using Run Distribution, there are no restrictions within WAVE on the number of parallel executions of the model.

RCAT 3D Catalyst: This three dimensional catalyst model brings new levels of accuracy and resolution to emissions simulation. Rapid calculation speed is achieved using optimized solvers for flow, heat transfer and chemistry. Multiple RCAT 3D catalysts can be used within a WAVE model with full interaction between them, as well as heat generated from catalytic reactions returned to the WAVE model. Results can be viewed in WAVE抯 new 3D postprocessor to visualise the light-off event within the catalyst brick.

Improvements to WaveMesher: The release of the original version of WaveMesher in version 5 was a major step forward in enabling customers to automatically create consistent and accurate WAVE models directly from CAD data. With WAVE v7, the WaveMesher is improved with the addition of an arbitrary cut plane capability, which greatly extends the type and range of geometry that can be processed. In addition, the implementation of orifice junctions in the automatically generated mesh, and improved algorithms for meshing as well as interface and methodology enhancements look set to make WaveMesher the tool of choice for those creating WAVE models from CAD data.

Improved Pre/Post Processing: WaveBuild抯 new Element Manager enables centralised creation and management of model elements. It also enables the organisation and reuse of elements within and between models using templates. FreeType fonts and imported logos enable users to enhance the appearance and branding of graphical output.

Diesel Particulate Filter: WAVE抯 emissions capabilities are further extended with the new 1-D model for wall-flow DPFs, which accounts for the collection of soot particles while the resultant pressure drop is controlled in the WAVE flow network. Filter regeneration strategies can be evaluated via cosimulation using an external model of the engine management system.
