Detailed Description

No-slip wall boundary condition.

Flips the sign of the velocity. Depending on the Thermal_type provided, will reflect either the heat flux or the internal energy about a given value.

Member Function Documentation

apply_advection()

void hexed::No_slip::apply_advection ( Boundary_connection & con )

overridevirtual

applies boundary condition to linear advection equation used to compute nonsmoothness indicator

Reimplemented from hexed::Flow_bc.

apply_flux()

void hexed::No_slip::apply_flux ( Boundary_connection & )

overridevirtual

applies boundary condition to viscous fluxes (if applicable)

Implements hexed::Flow_bc.

apply_state()

void hexed::No_slip::apply_state ( Boundary_connection & con )

overridevirtual

Note

apply_state must be called before apply_flux to prime state_cache

Implements hexed::Flow_bc.

n_prescribed()

int hexed::No_slip::n_prescribed ( int n_dim ) const

inlineoverridevirtual

Reimplemented from hexed::Flow_bc.

set_prescribed()

void hexed::No_slip::set_prescribed ( Interpreter & inter, Boundary_connection & con )

overridevirtual

Reimplemented from hexed::Flow_bc.

smooth()

bool hexed::No_slip::smooth ( ) const

inlineoverridevirtual

Returns false if this BC tends to cause the flow not to be smooth.

Farfield BCs should be expected to cause non-smoothness, especially if they are over-constrained, whereas wall boundary conditions should not. When performing AMR, cells on non-smooth boundaries will receive special treatment to avoid excessive refinement. So, when in doubt, have new boundary conditions return true so that they can be refined.

Implements hexed::Flow_bc.
