This project is developing algorithms to extend an adaptive computational fluid dynamics (CFD) solver to petaFLOPS performance.

This solver and others are enabled by developments in parallel, anisotropic adaptive meshing that afford a dramatic reduction in the elements required to accurately represent anisotropic physics. Both developments are guided by a petascale emulator that does not perturb the heap or stack memory, fits within an MPI layer, and predicts performance accurately in the presence of system faults.

The proposed applications will lead to a better understanding of the complex physics of turbulent flow, noise produced by turbulent flows, multiphase flows and the interaction of mechanics and biology in the human cardiovascular system. This fundamental scientific insight will be gained from high fidelity simulations that will be the first of their kind, and will be made possible by petascale resources and algorithms.
