15 C | SUBROUTINE CALC_COMMON_FACTORS
16 C | o Calculate common data (such as volume flux) for use
17 C | by "Right hand side" subroutines.
18 C *==========================================================*
19 C | Here, we calculate terms or spatially varying factors
20 C | that are used at various points in the "RHS" subroutines.
21 C | This reduces the amount of total work, total memory
22 C | and therefore execution time and is generally a good
23 C | idea.
