Function Documentation

◆ checkEntityIndexing()

void lf::mesh::test_utils::checkEntityIndexing ( const Mesh & mesh )

Function for testing mesh indexing (should be called from google test)

Parameters

mesh	A reference to the mesh to be checked

This function tests whether all entities of a mesh are indexed consecutively

◆ checkGeometryOrientation()

void lf::mesh::test_utils::checkGeometryOrientation ( const Entity & e )

Makes sure that the coordinates of the nodes obtained through e.SubEntities()[i].Geometry() match the ones obtained through e.Geometry()

Parameters

e	The entity to check.

◆ checkLocalTopology()

void lf::mesh::test_utils::checkLocalTopology ( const Entity & e )

Function for testing consistency of subentities.

Parameters

e	a (reference) to a mesh entity

This function verifies the consistency of the local topology, that is whether subentities of sub-entities are also subentities of the entity.

References lf::base::RefEl::Dimension(), lf::mesh::Entity::RefEl(), and lf::mesh::Entity::SubEntities().

◆ checkMeshCompleteness()

bool lf::mesh::test_utils::checkMeshCompleteness ( const Mesh & mesh )

Function testing topological completeness of a mesh.

Parameters

mesh	A reference to the mesh to be checked

All entities of dimension dim of a mesh must be subentities of at least one entity of dimension dim+1, if dim is smaller than the topological dimension of the mesh

Definition at line 13 of file check_mesh_completeness.cc.

References lf::mesh::Mesh::DimMesh(), lf::mesh::Mesh::Entities(), lf::mesh::Mesh::Index(), and lf::mesh::Mesh::NumEntities().

◆ checkRelCodim()

void lf::mesh::test_utils::checkRelCodim ( const Entity & e )

consistence check for local (relative) co-dimensions

Parameters

e	a (reference) to a mesh entity of any type

Implements a test whether dimensions of sub-entities match the relative dimension with which they are accessed through the Entity::SubEntities() method of lf::mesh::Entity.

◆ GenerateHybrid2DTestMesh()

std::shared_ptr< lf::mesh::Mesh > lf::mesh::test_utils::GenerateHybrid2DTestMesh	(	int	selector = 0,
		double	scale = 1.0 )

Generates a simple 2D hybrid test mesh.

Parameters

selector	integer parameter for the selection of test meshes
scale	factor for scaling all the coordinates in the meshes

The following line of code provides a pointer to the default test mesh:

#include "lf/mesh/test_utils/test_meshes.h"
...
auto mesh_p =
    lf::mesh::test_utils::GenerateHybrid2DTestMesh(selector,scale);

Test mesh selected with selector = 0: domain \([0.3]^2\)*scale
Test mesh generated when selector = 1;

This mesh contains parallelograms, that is, affine quadrilaterals.
Test mesh generated when selector = 3;

This is a purely triangular mesh
selector = 4: test mesh of [0,3]^2 with triangles and quads
selector = 5: test mesh of [0,3]^2 with triangles and parallelograms, all affine
selector = 6: hybrid mesh of a triangular domain
selector = 7: hybrid mesh comprising one quadrilateral and one triangle
selector = 8: hybrid mesh containing triangles and rectangles only.
