Changing the SWMM system Unit

Posted by MeHa on March 11, 2011 at 10:58am in SWMM5 GUI

Hi all,

Does any body know if it would be somehow possible to change system units of SWMM projects. For example,  if a project's input data was in british units, is there a way to change automatically all input and output values into SI unit.

    Hi, I could go few steps forward now. Using Excel tool I opened, I edited (inch to mm), closed, when asked to save I gave the same name as the temporary file (e.g. swm45E3.tmp), clicked yes for update. This works good for some projects, but some projects what I am getting is 'List index out of bounds ()' message after I finished all editing! what does this mean, and why does this happen?

      Hi, It works for me using SWMM 5.0.021 and these settings.  I can also open it in Excel if I save it as a Tab delimited file and then open up Excel using the INP file directly.  I looked at the INP file you sent to me and it did not have the TAB character so you probably did not save the file  with the Tab setting check-box on.

    Hi, It should show up as tab and thus in separate columns.  Have you told SWMM 5 that you inp file is tab delimited or should be saved with Tabs?

    Hi, You can use the Excel tool to convert the flow and other units to SI units but there is no tool directly to do the conversion for you.

      Hi Robert, I have another problem when working with the Excel tool. When I open the .inp file using the Excel tool, I am getting all the records in the first column of the resulting Excel sheet. Procedure I am using is (from the SWMM GUI:Tools-->Excel-->from excel I navigate to the .inp file-->from the message box that pops: Ichecked Separated,MS-DOS (PC-8), Tab-delimited, standard respectively. The excel file I am getting puts all the values in the first column, making editing difficult. I am using Excel-2007, any help?

      Thanx. Aditional reference to your post on ''SWMM 5 Tools'' also helped on how to add-in Excel to SWMM.
