[MITgcm-support] RBCS forcing period spec

[Jeffery R Scott]

Hi,


I'm trying to shift a repeating annual cycle of (monthly mean data) sss restoring as specified in file data (where it works) to data.rbcs.


In data:

 periodicExternalForcing=.TRUE.,

 externForcingPeriod=2592000.,

 externForcingCycle=31104000.,

 saltClimFile=   'sss25_128x60x12.bin',


In rbcs, following the manual example  8.3.2.4.1. Cyclic data in a single file


 rbcsForcingPeriod =2592000.,

 rbcsForcingCycle=31104000.,

 relaxSFile='sss25_128x60x12.bin',

(with default settings rbcsSingleTimeFiles<http://mitgcm.org/lxr/ident/MITgcm?_i=rbcsSingleTimeFiles> FALSE and ForcingOffset=0)


but I get this in STDERR

(PID.TID 0000.0001) *** ERROR ***  RBCS_READPARAMS: startTime before rbcsForcingOffset+0.5*rbcsForcingPeriod

(PID.TID 0000.0001) *** ERROR ***  RBCS_READPARAMS: will use last record

and then a crash attempting to access non-existing record. I would think it should average record 12 and record 1 at the start of the simulation
(nIter0 = 0) which is what I believe is done when restoring through data (?)

Either I'm misunderstanding something, or the manual is not correct, or I have something wrong somewhere (?)

Thanks,
Jeff
