Detailed Description

Defines a topological arrangement of a collection of "boxes" (e.g., parameter domains that map to physical-domain patches).

The information on outer boundaries is stored as a list of patchSide structs, each one defining the corresponding patch side to lie on the boundary.

The topological arrangement is stored as a list of boundaryInterface structs, each one defining an interface between two patch sides.

Member Function Documentation

gsProperty<T> addBoxProperty	(	const std::string &	name,
		T	t = `T()`
	)

inline

Adds a box property.

Parameters

[in]	name	The name of the property
[in]	t	The value of the property

Template Parameters

T	The type of the property

Returns: The property as a gsProperty object

std::vector< std::vector< patchComponent > > allComponents ( bool combineCorners = false ) const

Returns all components representing the topology.

Each entry of the outer vector represents one component (patch-interior, face, edge, corner, etc.). Since the components refering to one interface can be addressed as belonging to different patches, each component itself is represented by an inner vector which contains all patchComponent objects that refer to the particular component.

Parameters

combineCorners If this is set, all corners are treated as one component
