Classes
struct	MeltPoolDG::CompressibleFlow::ExternalFlowForce< dim, number, n_species >
	An abstract interface for defining external forces acting on the fluid that must be evaluated and incorporated during the cell loop of an explicit time integration scheme. More...
struct	MeltPoolDG::CompressibleFlow::ExternalFlowForceJacobian< dim, number, n_species >

Namespaces
namespace	MeltPoolDG
	Interface for a general preconditioner.
namespace	MeltPoolDG::CompressibleFlow
	This file contains various functions that can be used to set and evaluate boundary conditions for the compressible flow solver. The functions can be directly used with the BoundaryConditions class, which provides an interface to manage and evaluate the different boundary conditions in the solver.
