Function/Subroutine Documentation

mesh_local_findedge()

integer(i4) function mesh_local_findedge	(	class(oft_amesh), intent(in)	self,
		integer(i4), dimension(2), intent(in)	inds
	)

Find oriented edge connecting points i1 and i2.

Orientation is (+,-) if [imin,imax] is [i1,i2] or [i2,i1].

Parameters

[in]	self	Mesh to search
[in]	inds	Edge points (ordered)

Returns

Oriented edge linking inds(1) -> inds(2), zero if no edge exists

mesh_local_findface()

integer(i4) function mesh_local_findface	(	class(oft_mesh), intent(in)	self,
		integer(i4), dimension(:), intent(in)	inds
	)

Find oriented face with corner points i1, i2 and i3.

Orientation is (+,-) if [imin,imid,imax] is a (cyclic,anticyclic) permutation of [i1,i2,i3].

Parameters

[in]	self	Mesh to search
[in]	i1	Face 1st point
[in]	i2	Face 2nd point
[in]	i3	Face 3rd point

Returns

Oriented face linking i1 -> i2 -> i3, zero if no face exists

mesh_local_orient()

subroutine mesh_local_orient	(	class(oft_mesh), intent(in)	self,
		integer(i4), intent(in)	cell
	)

Create mapping from local points to boundary points.

Parameters

[in]	self	Mesh for mapping
[in,out]	a	Mapping array [np]
