In the engine development process, simulation and predictive programs have continuously gained in reliance. Due to the complexity of future internal combustion engines the application of simulation programs towards a reliable virtual engine development is a need that represents one of the greatest challenges.

Marco Chiodi presents an innovative 3D-CFD-tool, exclusively dedicated and optimized for the simulation of internal combustion engines. Thanks to improved or newly developed 3D-CFD-models for the description of engine processes, this tool ensures an efficient and reliable calculation also by using coarse 3D-CFD-meshes. Based on this approach the CPU-time can be reduced up to a factor 100 in comparison to traditional 3D-CFD-simulations. In addition an integrated and automatic evaluation tool establishes a comprehensive analysis of the relevant engine parameters. Due to the capability of a reliable virtual development of full-engines, this fast response 3D-CFD-tool makes a major contribution to the engine development process.
