Type 0 | Node i is a vertex of all terminal cells, ib ∈ {Ni}, which implies that it is not a hanging node. Type 0 nodes are further distinguished into two sub-types: | |
Type 0A | All ib ∈ {Ni} are of equal size. | |
Type 0B | The members ib ∈ {Ni} differ in size. | |
Type 1 | The node lies on the mid-edge of at least one terminal cell, ib ∈ {Ni}. | |
Type 2 | The node lies on the center of a terminal cell face of exactly one terminal cell, ib∈ {Ni}. |
