SWMM5 Export - Conversion Notes
This topic provides details of the export of the SWMM network objects, database items or model parameters which may be exported from a either SWMM network or a SWMM simulation to a section in an INP file. Miscellaneous export information can be found in the Other Exports section in this topic.
Data stored in native units will be converted and exported according to the flow units that are selected for the network in the Network flow units field in the Model Parameters Options.
Any exported comments are preceded by a pair of semi-colons (;;).

'Mfactor' values may be exported from a node's Pollutant inflow grid as well as from the profile properties in any SWMM Pollutograph event.
The Units factor in a SWMM Pollutograph event has been deprecated but retained for backwards compatibility. If an Mfactor is exported from a SWMM Pollutograph event as well as from its replacement Mass units factor in a node's Pollutant inflow property, and if either factor is a value other than 1, then both factors will be applied to the applicable pollutant inflow values on export. A message will be included in the applicable log file informing you of the name of the node and SWMM pollutograph for which a units factor has been applied twice.
