Hi all

I'm running a series of simulations with a coupled model (OpenIFS CY40R1 + NEMO/LIM2 v3.6 + OASIS3-MCT2.8). The first year seems to run fine, but when I try to restart the model I get the error 

GRIB_API ERROR : IO ERROR: No such file or directory: ICMSHKCM2INIT (No such file or directory)

I'm guessing the problem is that the initial conditions are not present (ICMSHKCM2INIT, ICMGGKCM2INIT, ICMGGKCM2INIUA). 

My question is, why are these files needed? It is a restart, so the "initial condition" should be the last step from the previous run, which is in the "srf" files. The "rcf" file is in the run directory, so OpenIFS should know it's a restart. 

Or are the INIT files always needed to set up the grid or something? If so, is there a control print somewhere in the NODE file so I can make sure OpenIFS is actually using the restart files for initial conditions? 


Cheers

    Hi Joakim,

    The model gets it's grid information and maybe the land-sea mask from the initial files. I'd need to check the model code to see exactly what's used but I know IFS gets it's grid information from the initial files.

    Yes, there is a entry in the NODE_001.01 logfile (I've just tried it) to confirm it's reading the srf* restart files:

    START CNT3
    READING RESTART FILES - STEP=000000072

    You'll also know the model is restarting because it will print a timestep number that follows from the previous run. Remember you need to increase NSTOP when doing restarts. If you do a first run with NSTOP=24 (say) with restarts enabled, unless you increase NSTOP on the restart the model will just read the restart files and stop because it thinks all the steps have been completed.

    Cheers,  Glenn

    Hi Glenn

    Thanks for the reply. I've looked, and there is a line

    START CNT3
    READING RESTART FILES - STEP=000008760

    in my NODE file, so it all seems correct then. I guess the INIT files are just needed for setting up the grid. 


    Have a good weekend!
