New York and London. July 16, 2014 CD-adapco?, the largest privately held CFD focused provider of Computer Aided Engineering software, today announced the release of v4.22 of STAR-CD® and es-ice? IC Engine simulation software. The v4.22 release provides extensive refinements to existing physics models and pre-processing developments to deliver rapid and more accurate in-cylinder simulation. es-ice has been enhanced with an automatic meshing capability for full cylinder models. Geometries can now be easily meshed with a minimum of inputs using one simple panel. Additional engine specific results, case details, and simulation settings have been added to the summary report and it is now possible to export an Excel workbook of the complete simulation post results. Automation has been further improved with the addition of several embedded Excel driven scripts. The complete sector simulation process and results animation and plotting processes can now be driven via Excel input and are available directly from within es-ice. Additionally, a full model can now be reflected from a trimmed half model to ensure perfect symmetry of the mesh. The ECFM-CLEH model has been extended to allow combustion of multi-component fuels or dual-fuel engines, including oxygenated fuels. As with ECFM-3Z, the ECFM-CLEH model uses a library-based approach to incorporate the effects of complex chemistry. In addition to

the libraries for standard fuels that are delivered to users, it is now also possible for users and other 3rd parties to generate their own fuel chemistry libraries for autoignition, laminar flame speed and equilibrium according to an open format provided by CD-adapco and providing they have appropriate chemistry mechanisms and software. Libraries for the CO model, which is part of ECFM-CLEH, are included in the installation. All libraries now use equivalence ratio rather than mixture fraction as one of the independent variables as this is more accurate for engine operating points with...

STAR-CD v4.22 provides a number of new capabilities to support the continued development of STAR-CD in-cylinder LES capability. Proper Orthogonal Decomposition (POD) is a powerful analysis technique for the quantitative analysis of LES calculations that can used to examine and compare different modes of a nominally cyclically-repeating flow and which is now available to the user. The improved Werner-Wengle wall model, which allows for SGS viscosity effects to be included in the fully turbulent region of the wall boundary layer, is now available. This simple yet effective model has been...
