mesh_handle

REMARK: Please note that this feature is still work-in-progress, so a lot of functionality is still missing, but will be added step by step.

In this folder, we define a mesh handle. Some application codes are designed for unstructured or uniform meshes and cannot use t8code's tree-based structures directly. For this purpose, an iterable mesh data structure is created as an intermediate level. This frees the users from having to work with the forest-of-trees based concept and increases the usability. Please note that it is not guaranteed that the mesh is conformal and does not contain hanging nodes.

If you want to use the handle, note that is has its own library. Turn the option T8CODE_BUILD_MESH_HANDLE to ON and link against the target T8_MESH_HANDLE in addition to the usual t8code target please.

The folder's most important files are:

• The mesh.hxx defines the mesh of the handle. This is the central file of the mesh handle.

• The element.hxx defines the elements (mesh or ghost elements) of the mesh handle.

• The competences.hxx defines additional competences/functionality of an element to access additional data.

• The constructor_wrappers.hxx allows to define a mesh handle using a cmesh instead of a forest and provides a very small number of examples where the user needs no cmesh.
