This keyword is used to create input data from a stationary calculation in NetSim to a dynamic calculation by the network. When keywords are entered in the DAT file, results file is created with the extension .sss. The SSS file contains geometry, pipe types and the ratio in the stationary calculation to pressure and flows in the pipe network.
FORMAT:
*DYNP <DynOpt>
Where:
DynOpt is an integer which defines which part of the pipe network must be shown in the SSS file.
- To include the supply pipes, enter 1
- To include the return pipes, enter 2
If the keyword is omitted, or DynOpt is set to 0 or *, the link will not be enabled. Otherwise an error message will be generated.
Unit conversion for pressure:
Pressure is given in the SSS file in mvp, while pressure in NetSim's power data file is given in kPa. To convert the pressures between the units kPa and mvp, the equation below is used:
p [mvp = p [kPa x 9.81
where p is pressure.
