Simulation Engine

"Provides the comprehensive model management solution demanded by today's Water supply engineers"

InfoWorks WS uses an enhanced version of the WesNet engine, world renowned for its speed and unparalleled control over the simulation. We detail below the reasons why it is the industry-leading solution.

Purpose built for Water Supply and Distribution Networks

Because it was developed specifically for analysing water supply and distribution networks, it does not suffer the drawbacks of being adapted from mathematical concepts developed for other utility industries such as Oil and Gas, or from the general network algorithms available in shareware.

Benchmarks show it's the fastest

Benchmark speed testing against other simulation engines shows InfoWorks WS to be significantly faster than any other water distribution engine (up to 10 times faster in some cases). The speed results from unique features in simulation process:

• The network to be simulated undergoes a pre- processing routine that significantly reduces the size of the mathematical problem to be solved.



• Critical or hydraulically difficult events do not stop the simulation or slow it down with forced intermediate timesteps. Errors are reported as exceptions that the user can review through detailed diagnostic outputs, to determine the precise nature of the problem in line with the acceptable simulation tolerance set.

Accurate "real world" modeling

The engine specifically offers comprehensive modeling of valve and pump behaviour rather than a simplified set of downstream hydraulic conditions offered by most other simulation packages. This advanced capability enables real life pump and valve behaviour to be truly modeled rather than merely represented. The simulated behaviour will then be valid over a far greater range of hydraulic conditions, not just those relating to the particular period of the calibration simulation.

Proven in thousands of projects

The engine has proved itself over thousands of network analysis projects world wide over many years since its original development, and is being continuously developed as new releases of InfoWorks WS are made. An increasing number of users are realising the productivity benefits of InfoWorks WS compared to 'standard' modeling engines.

In Summary

• InfoWorks WS uses an enhanced version of the WesNet engine and is the leading edge simulation engine for water supply and distribution modeling.



• The engine is a unique bespoke development for water supply modeling and does not suffer the inherent restrictions of modeling based on shareware engines or engines with their roots in other disciplines.



• Benchmark testing has shown the engine to be up to 10 times faster than other simulation engines.



• Real world pump and valve behaviour is modeled rather than relying on simplified downstream representations of hydraulic behaviour.



• The user has far greater control and feedback of the progress in terms of simulation tolerance, diagnostic feedback and general 'health' of the simulation.



• The engine is continuously being improved and developed in line with the InfoWorks WS release programme.
