Struct SlipWall 

pub struct SlipWall<const D: usize> { /* private fields */ }

A free-slip (far-field) wall on the face perpendicular to wall_axis (the max_side face when true, the zero face otherwise): no penetration (zero wall-normal flux — already the projection’s Neumann condition at a closed face) with a free tangential velocity (zero shear). It un-pins the face’s wall-tangential edges from the auto-derived no-slip set, so the boundary-clipped viscous operator gives the zero-shear condition. It is the lateral boundary an isolated body needs (a confining no-slip wall would impose a spurious boundary layer).

Implementations

impl<const D: usize> SlipWall<D>

pub fn new(wall_axis: usize, max_side: bool) -> Result<Self, PhysicsError>

A free-slip wall on wall_axis (max_side face).

Errors

PhysicsError::DimensionMismatch when wall_axis >= D.

Trait Implementations

impl<const D: usize, R: DecNsScalar> BoundaryZone<D, R> for SlipWall<D>

fn collect_slip_edges( &self, manifold: &Manifold<LatticeComplex<D, R>, R>, out: &mut Vec<usize>, )

Add this zone’s un-pinned (free-slip) edges: edges the auto-derived no-slip set would pin, but which this zone frees (a free-slip wall’s tangential edges, zero shear). The solver removes them from the no-slip set.

fn collect_rate_source( &self, _manifold: &Manifold<LatticeComplex<D, R>, R>, _acc: &mut [R], )

Add this zone’s forcing term to the rate source accumulator (edge cochain).

fn collect_constrained_edges( &self, _manifold: &Manifold<LatticeComplex<D, R>, R>, _out: &mut Vec<usize>, )

Add this zone’s zero-constrained edges.

fn collect_lift( &self, _manifold: &Manifold<LatticeComplex<D, R>, R>, _step: usize, _out: &mut Vec<(usize, R)>, )

Add this zone’s prescribed (inhomogeneous) edge values for march step step.

fn collect_prescribed_edges( &self, _manifold: &Manifold<LatticeComplex<D, R>, R>, _out: &mut Vec<usize>, )

Add this zone’s prescribed (inflow) edges, fixed at their field value.

fn collect_reference_vertices( &self, _manifold: &Manifold<LatticeComplex<D, R>, R>, _out: &mut Vec<usize>, )

Add this zone’s outflow pressure-reference vertices.
