DC Water Design Extension

Yes, 
of course, you can open the ASCII result files in Excel.
Eventually you have to adjust your EPANET settings to produce such files 
(Check
the  "Report" settings in EPANET).

Hi Stdeffen,

is there any other way of showing the epanet result than printing them to 
pdf? I mean like exporting the results directly from epanet to excel 
without using the *.dbf from arcview?
Regards

Hello All,

Martin had the problem that he was able to run a calculation
in Windows EPANET but not directly from ArcView. We tracked
the problem down to the patterns.

The instructions in the message below solved his problem.

Hi Martin,

the pattern file you attached looks like an EPANET file.
To use patterns with the DC Water Design Extension, you should use a format
like the one attached above (DBF does also work).

I was able to run your model successfully in Windows EPANET and directly from
ArcView. I assume that your pattern setup of the DC Water Design
Extension is wrong.
Please try the following:

* Save the attached file on your computer
* Open it as a table in ArcView (You have to set the file type to
"Delimited Text")
* Go to the view with your hydraulic model
* Register the pattern table with the DC Water Design Extension
(EPANET Tables Button)
* Run the calculation

Good Luck!

Steffen

Hi Steffen, thanks a lot for your help.

Each solution you suggested to any of my problems was working perfectly.

A "hurray" to the master of GIS  ;-)

regards
Martin

Hello All,

Martin asked if one has to receive its own posts to the mailing list.

You don't have to.
Mailman, the software that runs the mailing list offers a number of
configuration options.
Here's how you can change them:
Open the following page:

http://lists.sourceforge.net/lists/listinfo/dcwaterdesign-info

At the bottom of the page, enter your email address.
Click on the "Edit Options" button.

The option Martin is looking for is called:
" Receive posts you send to the list? "

You'll need your mailing list password. If you've lost it,
mailman can send it to you again (There's a button for this on the
configuration page).

Hi Martin,

> does anyone of you know how to get the X and Y- coordinates from a point
> theme into a proper table with an X-field and a Y-field without overtaking
> them manually? 

Add the X and Y fields (numeric) to your table).
Start Editing the table.
Select the X field.
Use the field calculator with the following formula:

[Shape].getX

Select the Y field

Use the field calculator with the following formula:

[Shape].getY

Is that what you were looking for?

Hello All,

I've just released version 1.2.6 of the DC Processing Extension.

This is a bugfix and robustness improvement release for the
node angle calculation and connection classification functions.

Sorry if the buggy version 1.2.5 caused any inconveniences for you.

Thanks to Mohammad for tracking down some of the bugs.

As always, the extension is available from 

http://dcwaterdesign.sourceforge.net

Steffen

P.S.: Mohammad, I think it would be good if you would subscribe to the
dcwaterdesign-info mailing list.

Dear all,
did anyone of you face the following problem:

After running a successful HNA in Epanet I wanted to run the same 
calculation from ArcView. The following error appeared:
 "Waited 20 sec for c:\.....name.bin, file did not appear"

The error seems somehow to be related to a time pattern which I defined in 
Epanet.
 Any Suggestions?

Thanks for your help

Regards from Tansania 
Martin

Hello All,

I've just released version 1.2.5 of the DC Processing Extension.

Here are the changes:

Bug fix for angle calculation. Angle calculation allows to enter an offset. 
Water network connection classification function for BoQ generation. 
More robust Segmentize Polylines function. 
New function Calculate Network Tree Names
New function Split Polylines by Polylines. 

The BoQ generation is basically working but needs some quality control
on the SQL script side and eventually additional documentation. If you
have to generate a BoQ right now, please contact me.

Regards,

Steffen

Hello All,

I've just released version 2.0.5 of the DC Sewer Design Extension.

The following things have changed:

Bug fix for profile creation (Endless loop error). 
Improved documentation.
Removed the "Enforce Maxiuml Line Length" function. Please use the
more powerful "Segmentize PolyLines" function of the DC Processing
Extension now.
Added documentation on water network profiles.
When creating profile, the data box height for CumulativeLineData and
LineData can be specified now.
Documentation on the creation of water network profiles. 
New function to link designed profile back to layout. 
Optional datum lines when creating profiles. 
Excavation calculation example in documentation. 

Thanks to Stephan for the documentation on the water network profiles.

Hello Stephan.

below is a snippet from an EPANET file containing a valve:

[VALVES]
;ID                     Node1                   Node2 Diameter Type 
Setting         MinorLoss 
 1                      1                       2                       12 
                PRV     0               0               ;

Looking at your screenshot, I cannot see the type definition of your 
valve. May it be that you've forgotten
to specify the valve type and the diameter?

Regarding your modified model (you converted the valves back to 
junctions): I had a similar problem
(Model runs in Windows EPANET, but not from ArcView) and I was able to 
track down the problem using the epanet
commandline version. However, this requires that I can reproduce the 
problem first. Note that you can
run the model in Windows EPANET and load the results to ArcView.
The ArcView error message
"A(n) Nil object not recognized"
is pretty generic and only indicates that ArcView or the DC Water Design 
Extension is not getting what it
expects at one point.

Tip 1: Copying the error message as text and pasting it to your email will 
drastically reduce the message size
and will allow you and others to search for this error message.
In your case, the error message was
Input Error 201: syntax error in following line of [Valve] section:

Tip 2: Describe what you want to do. You didn't mention what kind of valve 
you want to model
The DC Water Design Extension mentions 8 different types of valves with 
quite a different behaviour.
Not knowing what you need, I cannot help you.

Tip 3: Provide me with the necessary data to reproduce (and eventually fix 
the problem).

Tip 4: Address the mailing list. You may get much faster support from 
others working around the globe sharing
the same experiences as you. Most probably we'll also prevent others from 
having the same frustrating experiences
as you have. However send network data to me individually (or other which 
request it).

Tip 5: Always mention the versio number of the Software you're using. I 
assume you're using the DC Water Design
Extension 2.10+cvs-1

Tip 6: Don't mention that your support request is urgent. These cases I 
only solve at the end of the day.

Steffen

Stephan,

the easiest way to ensure that you have no duplicate IDs is the following:

Use the DC Processing Extension to calculate the field dc_id for all your 
model shapefiles (Make 
sure that you do this for all records in the shapefile).

Once this is done, you should prepend a unique prefix to each dc_id field 
in the different themes.
Example:

[dc_id] =
"j"+[dc_id]

for the junction theme.

[dc_id] =
"p" +[dc_id]

for the pipe theme.

Once this is done, run "Make EPANET Model" again and write your INP file.

Steffen

Checking the epanet model shows me many duplicated IDs - how to cleans 
them?

Hello All,

in addition to the maximum segment length, the Segmentize Polylines 
function
of the DC Processing Extension allows now to specify a minimum segment 
length
that is applied in those cases where the line is just a little bit longer 
than the maximum segment
length.

Note that lines that are shorter than the minimum segment length are not 
merged. To do this,
try the skeletonization function of the DC Water Design Extension.

If you need an snapshot of this version, let me know.

Steffen
