Wrote a paper on BOUT++ (BOUndary Turbulence), a parallel edge turbulence framework.
I added framework for physics-based preconditioning, advanced nonlinear solvers, advanced time-stepping methods, new mesh capabilities, and improved the build system for better software organization. The majority of the work involved improving meshing capabilities to add matrix preallocation for the non-contiguous branch-cuts. In addition, robust and novel IMEX (implicit-explicit) time-stepping methods were added giving the project competitive performance results. Version 1.0 incorporates my work.
