摘要

We present in this paper the recent developments implemented into the industrialCFD code AERLOG, developed at MATRA Defense for the use of aerodynamics studies on missile configurations with the financial support of the french MOD(Dret) and with the collaboration of the ONERA team for massively parallel implementation. The developments exposed in this paper concern both the numerical method and the parallel implementation aspects, and they represent the continuity of previous works. In the section 2, we recall a brief description of the main features of the code and of its implementation on parallel computers. The third section deals with an expansion of the multidomain approach through non conform interface: first from the numerical point of view. The fourth section is dedicated to the efforts handled towards the aim of a maximal portability: management of parallel input/output operations and introduction of an intermediate communication library. In the last section, some results of computing performances on a large scale MPP system are given and conclusions are drawn from this research study.
