Abstract
New engine development projects are involving much more numerical simulation than formerly and modern engineering requires flexible, accurate, easy-to-use computer codes. Since the commercial codes did not appear as fully satisfactory Renault, in collaboration with several partners, designed a new computer code based on modern methods. By the end of 1998, we expect that the simulation of a full engine cycle, starting from the CAD definition of the engine will require less than two weeks, on a standard 8-processor cluster of workstations. This article illustrates the use of the code and comparisons between an experiment and a numerical simulation are discussed.
