3.3.2 Boundary Grids
For each boundary between two adjacent segments a boundary grid is stored to
resolve the representation of identical points within these segments. This
allows to model discontinuities of physical quantities at the boundary.
Fig. 3.3 shows the boundaries between the segments of
the device shown in Fig. 3.1 and the corresponding index numbers.
Furthermore, the area at the junction of the two segments is stored for each
(a) Boundary between segment A and segment B.
(b) Boundary between segment B and segment C.
(c) Boundary between segment A and segment C.
Boundaries between the segments of the device shown in Fig. 3.1.
