[MITgcm-support] externalForcing fails at ini_params

[Jody Klymak]

Hi All,

Trying to set periodicExternalForcing and I'm failing on the following snippet from ini_params.F (line 872)


      ELSEIF ( INT(externForcingCycle/externForcingPeriod) .NE.
     &              externForcingCycle/externForcingPeriod ) THEN
        WRITE(msgBuf,'(A)')
     &   'S/R INI_PARMS: externForcingCycle <> N*externForcingPeriod'


my data file has:

 periodicExternalForcing=.TRUE.,
 externForcingPeriod=3720,
 externForcingCycle=7440,

which I'm pretty sure is an integer multiple of each other.  Obviously its a round-off error.  Is there some reason this check is so strict?  Or is there a compiler flag I should use to make comparisons like this be less strict?

The same check occurs in get_periodic_interval.F

Thanks,   Jody
