Hi dear Gerard Sanz

Thank you so much for your guidance.

You can find a programmers' toolkit in http://www.epa.gov/nrmrl/wswrd/dw/epanet.html. It contains the library of functions epanet2.dll. You can load this library from Matlab and combine your code and the EPANET functions.

Hi dear Gerard Sanz

Thank you so much for your guidance.

It is the EPANET Programmer's Toolkit.

I think it is useful for all users of EPANET. 

First of all, is good to know that EPANET toolkit is an open source available at https://www.epa.gov/water-research/epanet.

Then, you should be familiar with C coding, or MATLAB. I would recommend visiting the following GitHub profiles to get started:

http://community.wateranalytics.org/c/epanet

https://github.com/OpenWaterAnalytics/EPANET

Hope it helps!

Dear Dr. Jorge Pesantez,

Thanks a lot for your attention, time and prolific respond.

Best regards,

Mehdi
