Simulator expands to larger systems
The licence limit on the number of nodes in an InfoWorks network model has been doubled to 100,000.
The licence limit on the number of nodes in an InfoWorks network model has been doubled to 100,000 The expansion in network size limit applies to both the Water Supply and Collection System modules of InfoWorks, reflecting Wallingford Software's confidence in the speed and stability of its simulation engines

Software Models Complete Parisienne Water Cycle
Wallingford Software has installed its Info Works CS software with SIAAP, a major French collective in waste water management.
A number of InfoWorks users have already built network models beyond the previous limit of 50,000 nodes.
During the past year, Wallingford Software has been working with these users to ensure that models in the range 50,000-100,000 nodes can be run with the same confidence and accuracy as smaller models.
The largest of these, a completed 92,000-node model of Tokyo's collection systems, is now operational and tackling wastewater overflows.
Paul Banfield, Sales Director of Wallingford Software, explains: "There are two main issues relating to big models.
First, modelling all nodes in a single model, rather than selecting a subset or splitting the model into parts, reflects the performance of the network as closely as possible and requires fewer difficult assumptions to be made about skeletonisation, or how subnetworks join together.
So you get more reliable results.
In a recent article I argued that, as computers offer more desktop power, packages should use this to the benefit of water engineers by running better, larger models, and that is what we are achieving".
"However, second, the ability to run a large hydraulic model reliably depends also on the quality of the simulation engine.
Lesser engines become unstable over big data sets, with disastrous consequences.
In many ways the ability to run a big model reliably is a good indicator of the quality of the engineering mathematics of the package.
As far as I am aware, only InfoWorks can reliably run models of 100,000 nodes".
"We are making this announcement not as a promise for the future but as an established fact, as is our practice.
However, I would add that there is nothing in the mathematics of InfoWorks that places a practical limit on the size of network that it can accommodate, and I confidently expect that we will in future be raising the license limit well above 100,000 nodes".
