Macro Definition Documentation

T8_DTET_MAXLEVEL

#define T8_DTET_MAXLEVEL   21

The maximum refinement level allowed for a tetrahedron.

Must be smaller or equal to T8_DTRI_MAXLEVEL.

T8_DTRI_ROOT_BY_DTET_ROOT

#define T8_DTRI_ROOT_BY_DTET_ROOT   (1 << (T8_DTRI_MAXLEVEL - T8_DTET_MAXLEVEL))

The length of a triangle divided by the length of a tet.

This is useful to convert boundary coordinates from tet to tri.
