[MITgcm-support] About pickup

[elisabei]

Dear:

  I have a problem about the use of pickup file.

First step:I run the mitgcm using the monthly climatology initial fields and external forcing fields  about 10 years to get the stable model.

the data file show follow

 startTime=0,
 endTime=311040000,
 deltaTmom=60.0,
 deltaTtracer=240.0,
 deltaTClock =1200.0,
 pChkptFreq=31104000.,
 dumpFreq=259200.0,
 tauThetaClimRelax=864000.0,
 tauSaltClimRelax=864000.0,
 periodicExternalForcing=.TRUE.,
 externForcingPeriod=259200.,
 externForcingCycle=373248000.,
 zonalWindFile='dasilva_taux_12y.bin',
 meridWindFile='dasilva_tauy_12y.bin',
 thetaClimFile='lev_monthly_12y.bin',
 saltClimFile='lev_monthly_12y.bin',

Second step:I run the model using the really daily external forcing fields about 2 years to simulate the real ocean dynamical field. 

the data file show follow

 startTime=311040000,
 endTime=373248000,
 deltaTmom=60.0,
 deltaTtracer=240.0,
 deltaTClock =1200.0,
 pChkptFreq=259200.,
 dumpFreq=86400.0,
 tauThetaClimRelax=864000.0,
 tauSaltClimRelax=864000.0,
 periodicExternalForcing=.TRUE.,
 externForcingPeriod=86400.,
 externForcingCycle=373248000.,
 zonalWindFile='dasilva_taux_12y.bin',
 meridWindFile='dasilva_tauy_12y.bin',
 thetaClimFile='lev_monthly_12y.bin',
 saltClimFile='lev_monthly_12y.bin',

When I run the model at second step,the program prompt error "PGFIO-F-253/unformatted read/unit=9/attempt to read non-existent record (direct access).
 File name = OBE_U_1982_2014.bin    unformatted, direct access   record = 7084480 In source file mdsio_slice.f, at line number 3037".

I think the reason caused it is the change of the "externForcingPeriod" .

So would you like to tell me how can I do to solve the problem?
