C !INTRODUCTION: Kernel dynamical routines |
| 11 |
|
C This document summarises MITgcm code under the model/ subdirectory. |
| 12 |
|
C The code under model/ ( src/ and inc/ ) contains most of |
| 13 |
|
C the driver routines for the baseline forms of the kernel equations in the |
| 14 |
|
C MITgcm algorithm. Numerical code for much of the baseline forms of |
| 15 |
|
C these equations is also under the model/ directory. Other numerical code |
| 16 |
|
C used for the kernel equations is contained in packages in the pkg/ |
| 17 |
|
C directory tree. |
| 18 |
|
C Code for auxilliary equations and alternate dicretizations of the kernel |
| 19 |
|
C equations and algorithm can also be found in the pkg/ directory tree. |
