Member Function Documentation

virtual int apf::FieldShape::countNodesOn ( int type )

pure virtual

Return the number of nodes associated with an entity of this type.

in a linear mesh, nodes are associated with vertices but there are no nodes associated with other entities.

Parameters

type	select from apf::Mesh::Type

virtual EntityShape* apf::FieldShape::getEntityShape ( int type )

pure virtual

Get the sub-descriptor for this entity type.

Parameters

type	select from apf::Mesh::Type

virtual void apf::FieldShape::getNodeXi	(	int	type,
		int	node,
		Vector3 &	xi
	)

virtual

Get the parent element coordinates of an element node.

Parameters

type	element type, select from apf::Mesh::Type
node	index from element node ordering
xi	parent element coordinates

virtual int apf::FieldShape::getOrder ( )

pure virtual

Return the polynomial order of the shape functions.

this is not always applicable

virtual bool apf::FieldShape::hasNodesIn ( int dimension )

pure virtual

Return true iff there are nodes on entities of this dimension.

this is used to skip dimensions in loops
