Nalu-Wind - Verification Manual

Nalu-Wind represents a generalized unstructured, massively parallel, variable density turbulent flow capability designed for energy applications. This code base began as an effort to prototype Sierra Toolkit, [EWS+10], usage along with direct parallel matrix assembly to the Trilinos, [HBH+03], Epetra and Tpetra data structure. However, the simulation tool has evolved as a tool to support a variety of research projects germane to the energy sector including wind aerodynamic prediction and traditional gas-phase combustion applications.
