update README re: grdchk results

1 dgoldberg 1.1 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 dgoldberg 1.2 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 dgoldberg 1.3 3. solve_for_pressure.F modified to call the above, only when ALLOW_DIFFERENTIATE_CG2D_MATRIX is defined and ALLOW_CG2D_NSA is undefined (in ECCO_CPPOPTIONS).
8 dgoldberg 1.2
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 dgoldberg 1.3 7. shelfice_ad_diff.list in "main_branch_files" were modifief but do not seem to be required.
16    
17     8. output below for depth control. with temp0 or salt0 control, grdchk is accurate with NONLIN_FRSURF and nonlinearfreesurface=4.
