When the model time exceeds externForcingCycle, the model starts reading from the beginning of the forcing file. You are required to proved enough records (= externForcingCycle/externForcingPeriod)</div><div><br></div><div>Martin<br><div><br><blockquote type="cite"><div>On 9.

that the only options are either to have a periodic control, or an effectively time independent one. There is not a combination of options that allows a time varying nonperiodic control when the calendar package is not used (and possibly when it is), is my
understanding correct?</div>
