BEFORE a run of TRANSYT NetCon shows the input data file flows – indicated with bracketing. AFTER a run of TRANSYT, NetCon displays the flows as they appear in the OUTPUT file, NOT the input file, hence any changes will only be reflected in NetCon once a new TRANSYT run has been completed. The flows of a particular link can, for example, be less than the flow specified if there is oversaturation in any of the links feeding that particular link. The moral of the tale is – “If you are making changes to the data file remember to re-run TRANSYT before looking again at the NetCon diagram.
