So far, mizuRoute runs at the same time step as coupling time step (== coupling frequency, now set to 1 days). IRF routing is ok to run at whatever time step. dt_qsim In control file is reset to coupling frequency (coupling_period) in initializing phase.
With this PR, dt_qsim In control file is kept and mizuRoute run at this time step. dt_qsim is smaller than coupling_period, mizuRoute run with the same runoff input at nsub (coupling_period/dt_qsim) time, called sub-cycling. dt_qsim should be less than 86400 second.
One caveat.
Now, after sub-cycling, river volume is computed at last sub-time step is exported to the coupler, but what should be exported would be average over the coupling period?
This is for CESM coupled run.
