I don't know that it's evident either way, but I don't think you want the precursor changing as a function of time other than when the decay rate changes. If nothing else, I note that you don't change the precursor during the "INITIAL PERIOD FROM 1970 TO 2013", it's just 250. for the entire time period. In subsequent periods, the reservoir to the left has already decayed away to some lower value and you want to make it now decay at a lower rate; if you have the precursor changing at every timestep, I think you're double counting the decay. _______________________________________________ fipy mailing list [email protected] http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
