ElemType
Defines an enum for geometric element types.
The libMesh namespace provides an interface to certain functionality in the library.
The UnstructuredMesh class is derived from the MeshBase class.
void copy_tri_to_mesh(const triangulateio &triangle_data_input, UnstructuredMesh &mesh_output, const ElemType type)
Copies triangulation data computed by triangle from a triangulateio object to a LibMesh mesh...
void init(triangulateio &t)
Initializes the fields of t to NULL/0 as necessary.
DIE A HORRIBLE DEATH HERE typedef LIBMESH_DEFAULT_SCALAR_TYPE Real
void destroy(triangulateio &t, IO_Type)
Frees any memory which has been dynamically allocated by Triangle.
