The application of computational fluid dynamics (CFD) in the aerospace design process has increased dramatically over the last decade. This is due, in large part, to the relentless growth of computer performance. In some cases the enhanced computer power is used to perform high-resolution CFD calculations, in other cases it is used to create a virtual wind-tunnel where hundreds or thousands of lower resolution CFD computations are performed.
In either case, the total amount of data read during post processing is doubling every 18 months – in sync with Moore’s law. The data is generally stored on arrays of hard disk drives, and while hard disk capacity is keeping up with dataset size, the speed at which we can read the data is not.
