C---- This is a hack to get the right full pressure (from calc_phi_hyd) |
| 75 |
C in EOS when using useDynP_inEos_Zc ; the way to go arround would |
| 76 |
C be to store rhoInSitu in a common block and use it in calc_phi_hyd |
| 77 |
C (would also save one 3-D EOS computation + T & S storage for TAF). |
