Hello there! If you are new here, you might want tosubscribe to my newsletter for updates on this topic.

I have mentioned the EPANET toolkit several times before but didn’t

post any information about it yet. The following info is from the

toolkit readme file:

EPANET is a program that analyzes the

hydraulic and water quality behavior of water

distribution systems. The EPANET

Programmer’s Toolkit is a dynamic link library

(DLL) of functions that allows developers to

customize EPANET’s computational engine for

their own specific needs. The functions can be

incorporated into 32-bit Windows applications

written in C/C++, Delphi Pascal, Visual Basic,

or any other language that can call functions

within a Windows DLL. The Toolkit DLL file is

named EPANET2.DLL and is distributed with

EPANET. The Toolkit comes with several

different header files, function definition files,

and .lib files that simplify the task of interfacing

it with C/C++, Delphi, and Visual Basic code.

The freeware FireFlow utility was written using the EPANET toolkit.

For more information and download see EPANET web page.

How can I start modifying the source code of EPANET and

retrieve the result of hydraulic head available at the demand

node by using the toolkit functions of the EPANET for Head

Driven Analysis ?

I want to write program of EPANET with visual basic 2008 but i

don’t know function So I think you has example for program of

EPANET with visual basic 2008. Can you sent for me?

The toolkit functions allow you to call an entire simulation through

the ENepanet method, or run a time step by time step simulation.

The toolkit does not allow you to change the time step!

The toolkit is quite well documented. For hydraulic analysis, you

can use the loop (First declare longs t and tstep).

ENopen

ENopenH

ENinitH

while tstep 0

{

ENrunH( pointer to t)

(some toolkit functions to read or set the characteristics you

want and handle it with your algorithm)

ENnextH(pointer to tstep)

{

ENcloseH

ENclose

The only language I’m confident to know enough to take less time

coding than thinking of algorithms (when it comes to math only!)

is c#.net, so this is how the loop looks on c# given that the

wrapper class is called EpanetHandler.

EpanetHandler.ENopen(@”file.inp”, @”file.rpt”, @”file.out”);

EpanetHandler.ENopenH();

EpanetHandler.ENinitH(1);

while (tstep != 0)

{

EpanetHandler.ENrunH(ref t);

EpanetHandler.ENnextH(ref tstep);

}

EpanetHandler.ENsaveH();

EpanetHandler.ENcloseH();

EpanetHandler.ENclose();

The native function changes the values of tstep and t regardless

of what I do. This was a real moodkiller for me!
