Detailed Description

2-D grid system data.

This class is the key data structure for storing grid system data. To represent a grid system for fluid simulation, velocity field is defined as a face-centered (MAC) grid by default. It can also have additional scalar or vector attributes by adding extra data layer.

Constructor & Destructor Documentation

◆ GridSystemData2() [1/3]

CubbyFlow::GridSystemData2::GridSystemData2 ( )

Constructs empty grid system.

◆ GridSystemData2() [2/3]

CubbyFlow::GridSystemData2::GridSystemData2	(	const Size2 &	resolution,
		const Vector2D &	gridSpacing,
		const Vector2D &	origin
	)

Constructs a grid system with given resolution, grid spacing and origin.

This constructor builds the entire grid layers within the system. Note, the resolution is the grid resolution, not the data size of each grid. Depending on the layout of the grid, the data point may lie on different part of the grid (vertex, cell-center, or face-center), thus can have different array size internally. The resolution of the grid means the grid cell resolution.

Parameters

[in]	resolution	The resolution.
[in]	gridSpacing	The grid spacing.
[in]	origin	The origin.

◆ GridSystemData2() [3/3]

CubbyFlow::GridSystemData2::GridSystemData2 ( const GridSystemData2 & other )

Copy constructor.

◆ ~GridSystemData2()

virtual CubbyFlow::GridSystemData2::~GridSystemData2 ( )

virtual

Destructor.

Member Function Documentation

◆ AddAdvectableScalarData()

size_t CubbyFlow::GridSystemData2::AddAdvectableScalarData	(	const ScalarGridBuilder2Ptr &	builder,
		double	initialVal = `0.0`
	)

Adds an advectable scalar data grid by passing its builder and initial value.

This function adds a new scalar data grid. This layer is advectable, meaning that during the computation of fluid flow, this layer will follow the flow. For the future access of this layer, its index is returned.

Parameters

[in]	builder	The grid builder.
[in]	initialVal	The initial value.

Returns: Index of the data.

◆ AddAdvectableVectorData()

size_t CubbyFlow::GridSystemData2::AddAdvectableVectorData	(	const VectorGridBuilder2Ptr &	builder,
		const Vector2D &	initialVal = `Vector2D()`
	)

Adds an advectable vector data grid by passing its builder and initial value.

This function adds a new vector data grid. This layer is advectable, meaning that during the computation of fluid flow, this layer will follow the flow. For the future access of this layer, its index is returned.

Parameters

[in]	builder	The grid builder.
[in]	initialVal	The initial value.

Returns: Index of the data.

◆ AddScalarData()

size_t CubbyFlow::GridSystemData2::AddScalarData	(	const ScalarGridBuilder2Ptr &	builder,
		double	initialVal = `0.0`
	)

Adds a non-advectable scalar data grid by passing its builder and initial value.

This function adds a new scalar data grid. This layer is not advectable, meaning that during the computation of fluid flow, this layer won't follow the flow. For the future access of this layer, its index is returned.

Parameters

[in]	builder	The grid builder.
[in]	initialVal	The initial value.

Returns: Index of the data.

◆ AddVectorData()

size_t CubbyFlow::GridSystemData2::AddVectorData	(	const VectorGridBuilder2Ptr &	builder,
		const Vector2D &	initialVal = `Vector2D()`
	)

Adds a non-advectable vector data grid by passing its builder and initial value.

This function adds a new vector data grid. This layer is not advectable, meaning that during the computation of fluid flow, this layer won't follow the flow. For the future access of this layer, its index is returned.

Parameters

[in]	builder	The grid builder.
[in]	initialVal	The initial value.

Returns: Index of the data.

Returns the origin of the grid.

◆ GetResolution()

Size2 CubbyFlow::GridSystemData2::GetResolution ( ) const

Returns the resolution of the grid.

This function resizes the entire grid layers within the system. Note, the resolution is the grid resolution, not the data size of each grid. Depending on the layout of the grid, the data point may lie on different part of the grid (vertex, cell-center, or face-center), thus can have different array size internally. The resolution of the grid means the grid cell resolution.

Returns: Grid cell resolution.

◆ GetVelocityIndex()

size_t CubbyFlow::GridSystemData2::GetVelocityIndex ( ) const

Returns the index of the velocity field.

This class has velocity field by default, and it is part of the advectable vector data list. This function returns the index of the velocity field from the list.

Returns: Index of the velocity field.

◆ Resize()

		const Vector2D &	gridSpacing,
		const Vector2D &	origin
	)

Resizes the whole system with given resolution, grid spacing, and origin.

This function resizes the entire grid layers within the system. Note, the resolution is the grid resolution, not the data size of each grid. Depending on the layout of the grid, the data point may lie on different part of the grid (vertex, cell-center, or face-center), thus can have different array size internally. The resolution of the grid means the grid cell resolution.

Parameters
