VisSim version 9 has officially been released.

It comes with a variety of new features and improved robustness.

It's faster

Speed improvements have been made to large plots and overall simulation. Speed up of large diagrams with many conditional subsystems has also been greatly improved.

VisSim is helping to solve problems in far-flung places, including the Hawaiian islands. Francis Benevides, an electronics engineer and affiliate faculty member with the University of Hawaii at Hilo, has been using VisSim for a number of years to help monitor and contain a frog species that has invaded Hawaii and is threatening to alter two of the islands’ vulnerable ecosystems.

The frog in question

The frog in question is the coqui frog (Eleutherodactylus coqui). It arrived in Hawaii around 1988, probably on imported nursery plants.
