Dear Lionel,
This matter is explained in Appendix D of SWMM manual under the title of “Command line SWMM”. So in MATLAB you can use below format under DOS window:

Thanks Robert for your prompt help!

Hi Fateme Fallah,
I am doing something similar but in my case I am varying the infiltration factor. I am not very good with Matlab so require a bit of help on the coding. I would like to check if you have been successful in your attempt to…

Linking Matlab with SWMM5
Hi, I am currently trying to use Matlab to create a set of random values and inputting these random values into SWMM 5 to vary the different parameters (e.g. decay constant) so I will get a range of results. Has anyone done it before? Thanks!See More

Yeah, but what I am worrying is why the depth of the Tank 6 is not 8.51 m instead 8.26 m.

It seems to be working for me.

Hi, thanks a lot for the suggestion. I tried it and still got the same word printing instead of the variable values.
Then I tried with fprintf (f4, STO[0]); instead of fprintf (f4, "STO[0]"); which just gave me attached file.

Robert Dickinson replied to Upaka's discussion 'Writing results to an external file'
Hi, I am fairly certain that you need to open the file f4 at the start and close it at the end. It looks like you are opening, writing one line and then closing your file. You are writing a phrase instead of a variable.

Thank you very much. I will look XSECTION in detail. Thanks again.
Upaka replied to Upaka's discussion 'Variable for orifice height'
I am sorry, I think I didn't really explain the things. I just took an example for a subcatchment and showed the function. Likewise, I need to include a variable to the orifice height.

Variable for orifice height
Hi,I want to include a variable to the orifice height of my network and I tried to implement this through the source codes of SWMM 5.0. I am looking a particular function to do this. Please look at the following example. Manning´s roughness coefficient for the pervious areas of the subcatchments. (referring "subcatch.c") Subcatch[j].subArea[PERV].N = x[1];I believe x[1] is for the Manning's coefficient. Likewise what would be the function which can be used have the height of the…See More

Upaka replied to Upaka's discussion 'Time varying orifice heights'
OK thanks a lot. I think I have to enter the ratio between the depth at time "T" to full depth (depth at time T / Full depth) as the setting. This then surely should be between and 1.
Thanks again.
Robert Dickinson replied to Upaka's discussion 'Time varying orifice heights'
The orifice HEIGHT at any time is
Height - Link[j].xsect.yFull * Link[j].setting
where yFull is the full depth you entered and setting is the current setting based on the RTC rules (the setting is between 0 and 1)
Upaka replied to Upaka's discussion 'Time varying orifice heights'
Thanks for the reply.
You mean these opening setting are ratios?
Let's think the orifice full open height is 2 m. If I need to open it for 1.5 m, the entered number should be 1.5 / 2 = 0.75. Am I getting it correct?
Robert Dickinson replied to Upaka's discussion 'Time varying orifice heights'
The orifice and weir settings can only go from 0 (fully closed) to 1 (fully open). Your error was that you orifice settings greater than 1 - make them less than 1 and it will work.
