class Triangle : public Element

Data type triangle element

Inheritance:

Public Methods

Triangle( int *ind, int attr = 1 )

Constructs triangle by specifying the indices and the attribute.

Triangle( int ind1, int ind2, int ind3, int attr = 1 )

Constructs triangle by specifying the indices and the attribute.

int NeedRefinement( STable &v_to_v, int *middle) const

Return 1 if the element needs refinement in order to get conforming mesh.

virtual void SetVertices(const int *ind)

Set the vertices according to the given input.

virtual void MarkEdge(RectangularMatrix & pmat)

Reorder the vertices so that the longest edge is from vertex 0 to vertex 0

virtual void MarkEdge(const STable &v_to_v, const int *length)

Mark the longest edge by assuming/changing the order of the vertices.

virtual int GetType() const

Return element's type.

virtual void GetVertices( Array<int> &v ) const

Returns the indices of the element's vertices.

Triangle( int *ind, int attr = 1 )

Constructs triangle by specifying the indices and the attribute.

Triangle( int ind1, int ind2, int ind3, int attr = 1 )

Constructs triangle by specifying the indices and the attribute.

int NeedRefinement( STable &v_to_v, int *middle) const

Return 1 if the element needs refinement in order to get conforming mesh.

virtual void SetVertices(const int *ind)

Set the vertices according to the given input.

virtual void MarkEdge(RectangularMatrix & pmat)

Reorder the vertices so that the longest edge is from vertex 0 to vertex 0. If called it should be once from the mesh constructor, becouse the order may be used later for setting the edges. *

virtual void MarkEdge(const STable &v_to_v, const int *length)

Mark the longest edge by assuming/changing the order of the vertices.

virtual int GetType() const

Return element's type.

virtual void GetVertices( Array<int> &v ) const

Returns the indices of the element's vertices.

This class has no child classes.
