Nalu-Wind - Theory 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, :cite:`Edwards:2010`, usage along with direct parallel matrix assembly to the Trilinos, :cite:`Heroux:2003`, 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. .. toctree:: :numbered: :maxdepth: 2 lowMachNumberDerivation.rst supportedEquationSet.rst discretizationApproach.rst advectionStabilization.rst pressureStabilization.rst rteStabilization.rst nso.rst turbulenceModeling.rst boundaryConditions.rst overset.rst propertyEvaluation.rst couplingApproach.rst timeDiscretization.rst multiPhysics.rst windEnergy.rst topologicalSupport.rst adaptivity.rst codeAbstractions.rst
