Detailed Description

Abstract base class for 2-D boundary condition solver for grids.

This is a helper class to constrain the 2-D velocity field with given collider object. It also determines whether to open any domain boundaries. To control the friction level, tune the collider parameter.

Member Function Documentation

ConstrainVelocity()

virtual void CubbyFlow::GridBoundaryConditionSolver2::ConstrainVelocity ( FaceCenteredGrid2 *  velocity, unsigned int  extrapolationDepth = 5  )

pure virtual

Constrains the velocity field to conform the collider boundary.

Parameters

velocity	Input and output velocity grid.
extrapolationDepth	Number of inner-collider grid cells that velocity will get extrapolated.

Implemented in CubbyFlow::GridFractionalBoundaryConditionSolver2, and CubbyFlow::GridBlockedBoundaryConditionSolver2.

GetColliderSDF()

virtual ScalarField2Ptr CubbyFlow::GridBoundaryConditionSolver2::GetColliderSDF ( ) const

pure virtual

Returns the signed distance field of the collider.

Implemented in CubbyFlow::GridFractionalBoundaryConditionSolver2.

GetColliderVelocityField()

virtual VectorField2Ptr CubbyFlow::GridBoundaryConditionSolver2::GetColliderVelocityField ( ) const

pure virtual

OnColliderUpdated()

virtual void CubbyFlow::GridBoundaryConditionSolver2::OnColliderUpdated ( const Size2 &  gridSize, const Vector2D &  gridSpacing, const Vector2D &  gridOrigin  )

protectedpure virtual

Invoked when a new collider is set.

Implemented in CubbyFlow::GridFractionalBoundaryConditionSolver2, and CubbyFlow::GridBlockedBoundaryConditionSolver2.

SetClosedDomainBoundaryFlag()

void CubbyFlow::GridBoundaryConditionSolver2::SetClosedDomainBoundaryFlag

(

int

flag

)

Sets the closed domain boundary flag.

UpdateCollider()

void CubbyFlow::GridBoundaryConditionSolver2::UpdateCollider	(	const Collider2Ptr &	newCollider,
		const Size2 &	gridSize,
		const Vector2D &	gridSpacing,
		const Vector2D &	gridOrigin
	)

Applies new collider and build the internals.

This function is called to apply new collider and build the internal cache. To provide a hint to the cache, info for the expected velocity grid that will be constrained is provided.

Parameters

newCollider	New collider to apply.
gridSize	Size of the velocity grid to be constrained.
gridSpacing	Grid spacing of the velocity grid to be constrained.
gridOrigin	Origin of the velocity grid to be constrained.
