advanced simulation technologies Additional criteria were the involvement of each software provider in research projects, continuity in product development and maintenance and the opportunity to establish a successful long-term partnership with the supplier. Maik Suffa, Product Manager of AVL FIRE® states: “The result of the benchmark proves that AVL FIRE® ranks among the best available solutions in the area of flow simulations for engines and that AVL is acknowledged as a reliable partner of the automotive industry.” < 2 7 F O C U S AVL FIRE® WINS CFD BENCHMARK AT MAJOR GERMAN AUTOMOTIVE OEM AVL EXCITE ACOUSTICS – HIGHLY EFFICIENT SOUND RADIATION CALCULATION AVL EXCITE is the perfect platform for strength, durability and acoustic analysis of power units and drivelines. This is reflected by the majority of automotive OEMs and engine manufacturers worldwide who rely on EXCITE in their development process to improve product performance, reliability and safety. AVL proudly presents the newest addition to the EXCITE product family: EXCITE Acoustics, an innovative tool for the calculation of sound radiation in free field from vibrating structures such as engines and power units using the Wave Based Technique (WBT). Compared to presently used acoustic simulation solutions this methodology is resulting in a considerably enhanced computational efficiency. A unique automated patent-pending procedure has been developed to generate the acoustic mesh easily and fast with only a few clicks. EXCITE Acoustics seamlessly extends the EXCITE structural dynamic analysis workflow as the final step of acoustic analysis. It provides airborne noise results which are directly comparable with measured acoustic data and legal noise limits. Interfaces to common FE tools make EXCITE Acoustics an easy-to-integrate and valuable extension to complete your acoustic analysis workflow. < > Truck diesel engine: structure borne noise and sound pressure levels in 1 m distance at 2250 Hz > AVL FIRE® – an efficient tool for fluid dynamics simulation automotive OEMs, as a simulation tool in its engine development department. As part of the evaluation the participating software vendors performed typical simulation tasks taking place during the development of direct-injection spark ignition engines. Following that the vendors had the opportunity to present their products on-site. Besides the quality of the achieved calculation results, the assessment also included the effort to set up a computational case and the availability of simulation models. After evaluating five CFD software products for 18 months, AVL FIRE® will be used at BMW Group, one of the world’s leading
