Detailed Description

PDE systems manager.

This class manages a collection of PDEs and provides an interface to register PDEs. An incompressible N-S equation is always registered and treated as a special case. The remaining PDEs are created on-demand and are accessed through the equation systems vector.

Member Function Documentation

advance_states()

void amr_wind::pde::PDEMgr::advance_states

(

)

Advance states for all registered PDEs at the beginning of a timestep.

constant_density()

bool amr_wind::pde::PDEMgr::constant_density ( ) const

inline

fillpatch_state_fields()

void amr_wind::pde::PDEMgr::fillpatch_state_fields	(	const amrex::Real	time,
		const FieldState	fstate = FieldState::New
	)

Call fillpatch operator on state variables for all registered PDEs.

has_pde()

bool amr_wind::pde::PDEMgr::has_pde

(

const std::string &

pde_name

)

const

Query if a PDE has already been registered.

icns() [1/2]

PDEBase& amr_wind::pde::PDEMgr::icns ( )

inline

Return the incompressible Navier-Stokes instance.

icns() [2/2]

const PDEBase& amr_wind::pde::PDEMgr::icns ( ) const

inline
