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 ? Reply

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? Reply

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! Reply
