|
C REAL ARRAYS THAT COMPRISE "STATE": |

|
|
C H_streamice, |
| 282 |
|
|
C U_streamice, |
| 283 |
|
|
C V_streamice, |

|
|
C |
| 289 |
|
|
C visc & tau are now calculated based on U,V in streamice_vel_solve |
| 290 |
|
|
C but with Hybdrid stress formulation they will become part of |
| 291 |
|
|
C velocity initial guess, so they are kept |
