Function Documentation

element()

void hexed::hil_properties::element	(	Namespace &	space,
		Element &	elem )

Assigns the follwing variables:

• is_extruded: 1 if element is extruded, else 0
• n_dim: number of dimensions
• is_def = elem.get_is_deformed()
• ref_level = elem.refinement_level()
• aniso_ref_level = elem.aniso_ref_level()
• mask = elem.mask()
• nom_sz = elem.nominal_size() -uncertainty= elem.uncertainty
• center0, center1, center2: center of mass of vertices (not necessarily of the element itself)

position()

void hexed::hil_properties::position	(	Namespace &	space,
		Element &	elem,
		const Basis &	basis,
		int	i_qpoint )

Assigns the variables pos0, pos1, pos2

to the position of the i_qpointth quadrature point. Trailing dimensions are set to 0.

state()

void hexed::hil_properties::state	(	Namespace &	space,
		Element &	elem,
		int	i_qpoint )

Assigns the follwing variables:

• momentum0, momentum1, momentum2 : momentum per volume
• mass: mass per volume (aka density)
• energy: total energy per volume
• tss: time step scale
• art_visc: artificial viscosity coefficient
• residual_xxx for xxx in {momentum0, ..., energy}: residual of each of the conserved state variables

  Attention

  If Solver::update or Solver::update_art_visc_smoothness have been called since the last call to Solver::compute_residuals then the residual variables will be incorrect.

surface()

void hexed::hil_properties::surface	(	Namespace &	space,
		Boundary_connection &	con,
		int	i_fqpoint )

Assigns the follwing variables:

• pos0, pos, pos2: position
• normal0, normal1, normal2: unit surface normal (out of surface, into domain)
• momentum0, momentum1, momentum2 : momentum per volume
• mass: mass per volume (aka density)
• energy: total energy per volume
• visc_stress0, visc_stress1, visc_stress2 : viscous stress at surface
• mass_flux: diffusive mass flux through surface
• heat_flux: surface heat flux
