I can successfully run the primal form of incremental, strong constraint, 4-Dimensional Variational (4D-Var) data assimilation algorithm in the California Current System, 1/3 degree resolution, application (WC13).
Now I have a question for you:

If I complete the assimilation for 7 days, the model stops. And I want to continue assimilation on the next 7 days.
What should I do? I've tried to do this: NRREC == -1,ININAME == ***_rst.nc,just set up like non-assimilation.

However, errors are made in assimilation :( , as follows:

Code:
<<<< Descent Algorithm >>>>

  CG_DELTA not positive.
  CG_DELTA not positive.
  CG_DELTA not positive.
  CG_DELTA =   -227074.319591249      , outer =            1 , inner =
           1
  CG_DELTA =   -227074.319591249      , outer =            1 , inner =
           1
  CG_DELTA not positive.
  CG_DELTA not positive.
  CG_DELTA not positive.
  CG_DELTA =   -227074.319591249      , outer =            1 , inner =
           1
  CG_DELTA =   -227074.319591249      , outer =            1 , inner =
           1
  CG_DELTA =   -227074.319591249      , outer =            1 , inner =
           1
  CG_DELTA not positive.
  CG_DELTA not positive.
  CG_DELTA =   -227074.319591249      , outer =            1 , inner =
           1
  CG_DELTA not positive.
  CG_DELTA =   -227074.319591249      , outer =            1 , inner =
           1
  CG_DELTA =   -227074.319591249      , outer =            1 , inner =


Here is my output.file

Does anyone know the answer to the question?
