open .out file

Hello everyone,

I would like to read the .out file in a text editor created after a simulation in SWMM5.

However I can't get anything readable when I open the file in notepad or some equivalent software. As I would like to combine SWMM and Matlab, I need to see and understand the structure of the .out file...

Anyone knows how to do that?

  • Hello Nicolas,

    Normally, if you are using MATLAB the SWMM 5 Console program is used (SWMM5.EXE) and a Time Series RPT file is made

    Subject:   How to use SWMM 5 DOS to make an Output Table in the RPT file

    You can make tables of the node,  link  and  Subcatchment output data in SWMM 5 if you use the DOS SWMM 5 program but not the Windows DLL.   Step 1 is to create the DOS batch file, Step 2 is to select the nodes, links and subcatchments, Step 3 is to run the batch file and Step 4 is to view the RPT tables or extract the data to Excel.  You can do this directly in the InfoSWMM and H2OMAP SWMM graphical user interfaces by using Run Manager, Step 5 to select the nodes, links and subcatchments and Step 6 to view the tables in the browser. 

    Step 1.   Make a Batch File to call the DOS SWMM 5

    swmm5.exe Example1.inp  D:\swmm5.0.022\bob.rpt

    Step 2.  Add the nodes,  links and  subcatchments tables you want to generate in the RPT file

    CONTROLS         NO
    LINKS                 ALL
    NODES               ALL

    Step 3.  Run the Batch file

    Step 4.  Extract the Tables from the RPT File of SWMM 5

    Step 5.  InfoSWMM and H2OMAP SWMM dialog for selecting nodes, links and subcatchments for generating a detailed RPT file table.

    Step 6.  Sample InfoSWMM and H2OMAP SWMM RPT Tables if Report Options is used.

    • Great,thanks!


  • Hi, The OUT file is binary.  It would better if you try to use the text RPT file.

    • Hello Robert,

      If I'm not mistaken, the .RPT file provides general statistics and variables of the model but not the calculated time series.

      As I'm interested in the order in which the elements are written in the .out file, it doesn't help me that much. Do you have any clues on how to anticipate the place of the time serie in the .out file?

      Thanks for your help,
