News Using HPC (high performance computing) to solve Computational Fluid Dynamics (CFD) challenges has become common practice.

Another, more recent innovation, the cloud, has also enabled dramatic growth in total throughput.

This Amazon Web Services blog post highlights best practices for setting up an AWS HPC instance for running CFD (ANSYS Fluent in particular).
