Run SWMM Simulation
===================

Run a simulation from SWMM interface
------------------------------------
You can open the ``.inp`` file with SWMM and run the simulation from the interface.


Run a simulation with command line 
----------------------------------

.. code::
    
    {EXEPATH}\swmm5.exe {INPUTPATH}\{INPUTFILENAME}.inp {OUTPUTPATH}\{REPORTFILENAME}.rpt {OUTPUTPATH}\{OUTPUTFILENAME}.out


Run a simulation with QGEP-SWMM
-------------------------------

The path to the SWMM executable must be set in the Processsing tools options. The plugin will launch the command line in the background.

Launch ``SWMM Execute``:

- ``INP file``: the ``.inp`` file generated during the previous step
- ``RPT file``: the output report file ``.rpt`` containing the results (summary and full time serie)
