How are fast turnaround times achieved with Code Leo?

We apply a number of techniques to achieve fast turnaround time.  Local time stepping is employed, as well as pre-conditioning with gauge pressure to speed up convergence for low speed flow problems.  We also employ two convergence acceleration techniques: a residual propagation method for unstructured mesh, and a multi-grid scheme for structured mesh.  For time accurate simulations that employ wall integration, we employ dual time stepping to facilitate convergence.

Finally, for highly skewed meshes, our cell-vertex numerical scheme produces accurate results with fewer elements compared to cell-centered schemes.  The need for fewer elements under this condition also results in improved turnaround time.
