Abstract
Since many years, Aerospatiale is involved in the validation of Navier-Stokes codes for the design of transport aircrafts, especially for engine airframe integration, current responsability of Aerospatiale within the Airbus worksharing. In order to deal with the complex geometries encountered, the NSMB code has been developped in cooperation with EPFL, CERFACS, KTH and SAAB. In order to bring the costs of Navier-Stokes computations around complete aircrafts down to an acceptable level for the design engineers, the parallelization of NSMB has been undertaken within the framework of EUROPORT-1/Parallel Aero project. One of the three industrial test cases defined for the validation of parallel-NSMB is the challenging transonic flow around the AS28G wing/body/pylon/nacelle configuration, for which Aerospatiale has realized a 62 blocks structured multiblock mesh of about 3.5 millions nodes. A reference solution obtained on one node of Aerospatiale's CRAY/J916 is presented. Performance results from parallel calculations using up to 16 nodes of the CRAY/J916 are given. The benefits of high performance computing are discussed from the point of view of the industrial end-user.
