– B.8 – Fig. B.1 Example of a computational domain having (17 �11 � 7) cells and 7 boundary specifications. Consider a computational domain shown in Fig. B.1. There are 17 �11 � 7 cells in the x, y, and z directions, respectively. The corresponding number of cell vertices is thus 18 �12 � 8 and of nodes is 19 �13 � 9. In data #28 (nx, ny, nz) of the KECONTROL, the following values are specified: #28: 18 12 8 There are 7 boundary types: B1 (blocked cells), B2 (inlet), B3 (outlet), B4 (channel side wall), B5 (symmetry plane), B6 (channel bed), and B7 (water surface). In data #36 (nrbnd) of the KECONTROL, the following is specified: #36: 7 This input is then followed by 3-lines boundary specifications, #37 (cbnd 1, cbnd 2), #38 (istart, iend, jstart, jend, kstart, kend), and #39 (rks), to be inputted for each boundaries. The boundary type (cbnd 1) is either:
BLO for blocked cells, INL for inlet, OUT for outlet, WAL for wall boundaries, SYM for symmetry planes, or FRE for free surfaces. The boundary position (cbnd 2) is either: EAS for east face, WEA for west face, NOR for north face, SOU for south face, TOP for top face, or BOT for bottom face. – B.9 – Note that the cbnd must be written in either upper case or lower case letters, but not mixed ones. For the boundary specifications shown in Fig. B.1, the following data must be inputted: #37: blo blo #38: 9 11 7 8 2 8 #39: 0.22E-3 #37: inl wea #38: 2 2 2 12 2 8 #39: 0.0 #37: out eas #38: 18 18 2 12 2 8 #39: 0.0 #37: wal sou #38: 2 18 2 2 2 8 #39: 0.22E-3 #37: sym nor #38: 2 18 12 12 2 8 #39: 0.0 #37: wal bot #38: 2 18 2 12 2 2 #39: 4.2E-3 #37: fre top #38: 2 18 2 12 8 8 #39: 0.0 B.2.2 KECOORDINA #1 title A string of 100 characters.
