A Tool for Practical Simplification of Water Networks Models

This paper presents development of water network model reduction software, Simplifier2. The application can be integrated with other concepts applied to water distribution system or it can be used as a standalone tool for the purpose of the model simplification only. The utilisation of parallel programming techniques and sparse matrices ordering algorithms drastically increased the speed of simplification. Simplifier2 is able to reduce the water network model, consisting of several thousand elements, in less than 1 minute calculation time. Simplifier2 has been already successfully utilised in a number of research and commercial projects.
