C | o Calculate common data (such as volume flux) for use | |

C | by "Right hand side" subroutines. | |

C |==========================================================| |

|
|
C | Here, we calculate terms or spatially varying factors | |
| 18 |
|
|
C | that are used at various points in the "RHS" subroutines.| |
| 19 |
|
|
C | This reduces the amount of total work, total memory | |
| 20 |
|
|
C | and therefore execution time and is generally a good | |
| 21 |
|
|
C | idea. | |
