InfoSewer and H2OMAP Sewer New Features in 2011

Subject: InfoSewer and H2OMAP Sewer New Features in 2011

InfoSewer for Arc GIS 9 and 10 and  H2OMAP Sewer had a many engine and GUI enhancements during 2011 to allow the programs to work better for models up to 50,000 elements that simulate water quality and hydrology.  The improvements now allow large models to be run with smaller report and simulation time steps and provide a Mass Balance Check  at the end of the report file for the user to easily check the model results.  The new ForceMain Solution for EPS simulations now allows the simulation of complicated Force Main Loops in the network without the need for making simplifying network connection assumptions.  The engine changes make InfoSewer andH2OMAP Sewer more robust for large models and small time steps while  providing better solution error checking and routing.  The enhanced Output Report Manager shows all of the possible Node and  Link Output Variables in Graphs, Tables and Advanced HGL Labeling.  The year 2011 was a year in which the internal engine of InfoSewer and H2OMAP Sewer were improved and also a year in which more simulation output information was shown to the user so that they can both understand and explain the modeling results in a more confident fashion.
