Meaning Run Status

Posted by Ridwan Sami on August 7, 2016 at 7:55pm in SWMM5
How to describe run status for continuity error, for instance "Suface Runoff -0.25% and flow routing -0.10%. Can you describe what the menaning of the result? Why should be negative in value?

    The same comments apply to both runoff and flow routing continuity.,

    The same  comment applies to the total continuity error

           FlowTotals.pctError = 100.0 * (1.0 - totalOutflow / totalInflow);

    The CE is just the Inflow - Outflow

      x = 1.0 - NodeOutflow[j] / NodeInflow[j];

    If the total  inflow is greater than the outflow then the error  will  be positive

    IF the total   inflow is less  than the outflow  then the error  will be negative

      Yes I got it runoff continuity error. And how about the flow routing contuinity error?
