NOTES ON SETUP |
| 2 |
|
| 3 |
1. cg2d_no_nsa.F should be exactly like cg2d.F -- but EXCH_S3D needed to be replaced by EXCH_XY_RL o/w the forward model crashed |
| 4 |
|
| 5 |
2. cg2d.flow sets adjoint of cg2d_no_nsa to adcg2d_no_nsa -- this is the only reason cg2d_no_nsa.F even needs to exist |
| 6 |
|
| 7 |
3. solve_for_pressure.F modified to call the above, only when ALLOW_DIFFERENTIATE_CG2D_MATRIX is defined (in ECCO_CPPOPTIONS). |
| 8 |
|
| 9 |
4. adcg2d_no_nsa finds adjoint of cg2d_b_ad as well as ac2d_ad etc. Needs common block from ad_taf_output.f to affect the latter. harcoded. |
| 10 |
|
| 11 |
5. if line 312 of solve_for_pressure.F not included, mitgcmuv_ad will crash in forward pass (ac2d etc takes on different values -- don't know why) |
| 12 |
|
| 13 |
6. line 212 of obcs_fields_load.F commented; if not, there are extensive recomputation errors in taf_ad.log i cannot fix. |
| 14 |
|
| 15 |
7. shelfice_ad_diff.list in "main_branch_files" may be required. |
