An error message appears : '***ERROR: input file needs to contain GRiB1 formatted messages' I found that the problem comes from the file ""gridcheck.f90"": ! ! GET NEXT FIELDS ! call grib_new_from_file(ifile,igrib,iret) if (iret.eq.GRIB_END_OF_FILE ) then goto 30 ! EOF DETECTED I can not find why it does not work. I can make it work by modifying gridcheck.f90 and writing a list of every name of the wind field that will be used for the run, but this is constraining and I am not sure how many fields are taken into account for the spin up.
