Abstract
Application of large-scale parallel computational fluid dynamics to industrial problems is discussed, with its focus on vehicle aerodynamics. Issues to realize the industrial CFD using high-performance computing environment are mentioned in the context of mesh generation and the peak performance of application software. Capability and limitations of both unstructured and structured grids are demonstrated by considering the complicated and deficient CAD geometry data used in real product development process and the near future computer architecture. Finally it is discussed that how such HPC-CFD helps to realize innovative industrial processes.
