The pre processing priority in fluid dynamics design

Abstract

In the last years, thanks to the development of computational capabilities, the CAE methodology has become an essential tool in the design especially in the preliminary phase and configuration analysis. This happens also and above all in the fluid dynamic design by using CFD codes, which have reached high levels of reliability. In recent years the simulation times have significantly reduced and this means that the preprocessing phase has become the real bottleneck within the project. The engineering consulting companies can face trouble to define standard methodologies for the analysis, because of the wide range of application fields, and need to reduce operational costs and response times to be competitive. This kind of problems induce us to find a strategy to automate the entire design process as much as possible. This work aims at showing the use of ANSA tools for our cases, and the development of preprocessing automation methods easily adaptable to most of them.
