Function Documentation

getOrientation()

array_type::tensor< int, 1 > GooseFEM::Mesh::Tri3::getOrientation ( const array_type::tensor< double, 2 > & coor, const array_type::tensor< size_t, 2 > & conn )

inline

Read the orientation of a mesh of triangular elements of type ElementType::Tri3.

Parameters

coor	Nodal coordinates [nnode, ndim].
conn	Connectivity [nelem, nne].

Returns

Orientation (-1 or +1) per element [nelem].

setOrientation() [1/2]

array_type::tensor< size_t, 2 > GooseFEM::Mesh::Tri3::setOrientation ( const array_type::tensor< double, 2 > & coor, const array_type::tensor< size_t, 2 > & conn, const array_type::tensor< int, 1 > & val, int orientation = -1 )

inline

Set the orientation of a mesh of triangular elements of type ElementType::Tri3.

For efficiency this function reuses the output of getOrientation().

Parameters

coor	Nodal coordinates [nnode, ndim].
conn	Connectivity [nelem, nne].
val	Current orientation per element (output of getOrientation()) [nelem].
orientation	Target orientation (applied to all elements).

Returns

Connectivity (order of nodes-per-element may have changed) [nelem, nne].

Definition at line 279 of file MeshTri3.h.

setOrientation() [2/2]

array_type::tensor< size_t, 2 > GooseFEM::Mesh::Tri3::setOrientation ( const array_type::tensor< double, 2 > & coor, const array_type::tensor< size_t, 2 > & conn, int orientation = -1 )

inline

Set the orientation of a mesh of triangular elements of type ElementType::Tri3.

Parameters

coor	Nodal coordinates [nnode, ndim].
conn	Connectivity [nelem, nne].
orientation	Target orientation (applied to all elements).

Returns

Connectivity (order of nodes-per-element may have changed) [nelem, nne].
