4 C /==========================================================\
5 C | CG3D.h |
6 C | o Three-dimensional conjugate gradient solver header. |
7 C |==========================================================|
8 C | The common blocks set up here are used in the elliptic |
9 C | equation inversion. They are also used as the interface |
10 C | to the rest of the model. To set the source term for the |
11 C | solver set the appropriate array below. To read the |
12 C | solution read from the appropriate array below. |
