cashocs.geometry.mesh_testing.IntersectionTester#

class cashocs.geometry.mesh_testing.IntersectionTester(
mesh: fenics.Mesh,
)[source]#

Bases: object

A class for testing the mesh after it has been modified.

Initializes the posterior mesh tester.

Parameters:

mesh (fenics.Mesh) – The mesh that is to be tested.

Methods Summary

test()

Checks the quality of the transformation after the actual mesh is moved.

Methods Documentation

test() → bool[source]#

Checks the quality of the transformation after the actual mesh is moved.

Checks whether the mesh is a valid finite element mesh after it has been moved, i.e., if there are no overlapping or self intersecting elements.

Returns:

True if the test is successful, False otherwise.

Return type:

bool

Notes

fenics itself does not check whether the used mesh is a valid finite element mesh, so this check has to be done manually.
