| With pro-STAR version v4, the input formats have changed radically. |
| * Easier to parse space-delimited input formats |
| * No arbitrary or integral couples |
| * No trimmed or degenerate cells |
| * Support for polyhedral cells |
| * Boundaries are directly connected to cell and faces |
|
|
| Since the boundaries are now connected directly to the faces, |
| we now must be concerned with cell face notation otherwise we perform the |
| incorrect lookup. |
| Fortunately, there are only 4 primitive shapes to be concerned with. |

| Hexa: |
| Foam pro-STAR |
| ~~~~~~~~~~~~~~ ~~~~~~~~~~~ |
| Face 0 (0 4 7 3) -> F5: (0 4 7 3) |
| Face 1 (1 2 6 5) -> F6: (1 2 6 5) |
| Face 2 (0 1 5 4) -> F3: (0 1 5 4) |
| Face 3 (3 7 6 2) -> F4: (2 3 7 6) |
| Face 4 (0 3 2 1) -> F1: (0 3 2 1) |
| Face 5 (4 5 6 7) -> F2: (4 5 6 7) |

| Prism: |
| Foam pro-STAR |
| ~~~~~~~~~~~~~~ ~~~~~~~~~~~ |
| Face 0 (0 2 1) -> F1: (0 2 1) |
| Face 1 (3 4 5) -> F2: (3 4 5) |
| Face 2 (0 3 5 2) -> F5: (0 3 5 2) |
| Face 3 (1 2 5 4) -> F6: (1 2 5 4) |
| Face 4 (0 1 4 3) -> F3: (0 1 4 3) |
|

|
| Tetra: |
| Foam pro-STAR |
| ~~~~~~~~~~~~~~ ~~~~~~~~~~~ |
| Face 0 (1 2 3) -> F6: (1 2 3) |
| Face 1 (0 3 2) -> F5: (0 3 2) |
| Face 2 (0 1 3) -> F3: (0 1 3) |
| Face 3 (0 2 1) -> F1: (0 2 1) |
|

|
| Pyramid: |
| Foam pro-STAR |
| ~~~~~~~~~~~~~~ ~~~~~~~~~~~ |
| Face 0 (0 3 2 1) -> F1: (0 3 2 1) |
| Face 1 (0 4 3) -> F5: (0 4 3) |
| Face 2 (3 4 2) -> F4: (2 3 4) |
| Face 3 (1 2 4) -> F6: (1 2 4) |
| Face 4 (0 1 4) -> F3: (0 1 4) |
|
|
| Noting that several faces are skipped over in the pro-STAR definitions, |
| simply introducing a new cell modeller will be a problem. |
| Instead, subtract 1 from the pro-STAR faces and use lookup tables. |
