Thanks Rui for your time and efforts to go through this project, By using GIS functions and adding fields in attribute files, the sub catchments are now linked with their appropriate outlets.  Also, rather than, loading all hydrologic and…

Thanks Robert, It really what I needed - without reading the manual, I was trying each option in the swmm to see if there is way to export the data in excel format. However, data being too large, excel simply says sorry with this message (This…

Please try inp.PINS and select inpTools --> Subcatchments connection (https://sites.google.com/site/inppins/) You can also edit inp text file, or even use GIS functions.

inp.PINS worked just fine! Kashif, Please see the message I send you with my results data. The data you send me needed to be "SWMM formated". I did some of this: 1 - Assign invert elevation to nodes from links shp - GIS join; 2 - Define…

Maximum Surcharge Height Over Crown Explanation

Note:   Maximum Surcharge Height Over Crown Explanation Here is an example of how the Maximum Surcharge Height over the Node Crown is calculated.     Consider a manhole with an invert of 10 feet,  one incoming pipe (Pipe A), one outgoing pipe (Pipe B), both pipes with a diameter of 2 feet, but the invert  of Pipe A is 10 feet and the invert of Pipe B is 11 feet.  What is the Maximum Surcharge height if the HGL at the node is 17…See More

10,000+ subcatchments to be assigned with outlets

Hi experts,I am to assign outlet to some 10,000 sub catchments, manually doing it doesn't seem professional.Luckily, name of subcatchment is same name of junction (outlet)i.e.Subcatcment              Junction177119                      177119177123                      177123177126                      177126263803                      263803263806                      263806These are not in particular sequence but name of subcatchment is always same as of junction.Any clueThanks in advanceSee More

"GetSwmmResults" function

  • Rating: No Rating
Hi,
I am bit confused on calling the results of the SWWM using the above function. 
Interfacing guide explains it as follows; but I guess I am confusing specially shown at bold-italic letters.
If anyone knows how to call the results using the above function please be kind enough to explain me using an example.

Thanks alot.
Upaka



The function GetSingleResult, which is included in the example code files that accompany this guide, demonstrates the
code needed to retrieve the computed result for a particular variable for a
given object at a specific point in time. The arguments to the function are:
itemType
the class of item being sought (input)
itemIndex
the index of the item being sought (input)
varIndex
the index of the variable being sought (input)
period
the index of the time period being sought, starting from 1(input)
value
the value of the result being sought (output).


The function returns a value of 1 if it was successful or a value of 0 if was not.

The choices for itemType can be:
· 0 for Subcatchments,  
· 1 for Nodes  
· 2 for Links  
· 3 for System  

The itemIndex argument identifies items of a given class that are reported on by consecutive numbers
starting from 0, which are assigned in the same order as the item appeared in
the SWMM 5 input file. As an example, suppose that a system contains 5 junction
nodes with ID names J1, J2, J3, J4, and J5 that are listed in this same order in
the project's input file, but output results are only requested for junctions J2
and J4. Then an itemIndex of 0
would retrieve results for J2 while an itemIndex of 1 would
do the same for J4. Any other values for itemIndex would be
invalid. For System items the itemIndex argument
is ignored.

Hi, Are you getting this code from the Delphi code of SWMM 5?
Robert DickinsonPermalink Reply by Robert Dickinson on August 5, 2010 at 6:43am
There is a feature in SWMM 5 that allows you to either save ALL of the junction information or only a portion of the junction information. If you just save two junctions then you can only retrieve the values from two junctions.

Hi,
Thanks for the replies.

I am using Microsoft Visual C++ 6.0 to get the results (I mean linking SWMM to another software and to call the results) using C++. (I have downloaded the SWMM5.0 interfacing guide from the EPA web site)

Think I should explain more the problem what I have.

Let us assume there are 5 weirs and 2 orifices at one problem and I wanna get the flow rate through the weirs.

Is the following coding in c++ correct?

OpenSwmmOutFile("f3.out");

GetSwmmResults(2, 1, 0, t, A);

GetSwmmResults(2, 2, 0, t, B);

GetSwmmResults(2, 3, 0, t, C);

GetSwmmResults(2, 4, 0, t, D);

GetSwmmResults(2, 5, 0, t, E);

CloseSwmmOutFile();

In this case I am not sure how I can use the "itemIndex" which is the second number. Since both weirs and orifices are under the category of links it is bit confusing.

Thanks alot.

Can you please explain this particular feature on saving portion of the junction information?
Thanks
UpakaPermalink Reply by Upaka on August 11, 2010 at 11:36am
I found the answer for my own question and would like paste it here if anyone needs it in future.


When results for all links are saved, then the ItemIndex is the order
(starting from 0) in which the Link is first defined in the input file.
For example, suppose your input file looked as follows:

[CONDUITS]
A
B
C

[WEIRS]
W1
W2

]PUMPS]
P1
P2

[ORIFICES]
O-A
O-B

Then the ItemIndex for weir W1 would be 3 while that for orifice O-B is
8.

If in the [REPORT] section you specify that results are only saved for
weir W1 and orifices O-A and O-B, then the item index of W1 is 0 and
that of O-B is 2 (even if you listed them as O-B, W1, and O-A in the
[REPORT] section, since the numbering is still relative to their
position where they are first defined in the input file).
