Welcome to the Adept Scientific Press Room

Adept Scientific is pleased to announce the release of VisSim Version 6.0 for Windows 95/98/2000/NT/XP from Visual Solutions Incorporated (VSI). VisSim 6.0 is the latest version of the award-winning, Windows-based program for the modelling and simulation of complex nonlinear dynamic systems. It combines an intuitive drag and drop block diagram interface with a powerful simulation engine, making it the fastest and easiest-to-use simulation and embedded system design software available.

VisSim Version 6.0 adds new blocks, an improved simulation engine, and enhanced user interface. The new blocks read and write audio from .WAV files or a Windows audio device enable the user to control the delay for the ‘on’ and ‘off’ commands found in process control. Other new blocks identify the location and value of the minimum and maximum elements of a matrix, give the time of day, and display a coloured bit for every element in a matrix.

The new Maple interface blocks communicate with Maple mathematical problem-solving software. These blocks allow the reading and writing of scalar and matrix data to the Maple workspace, as well as execution of Maple scripts. This brings a fast smooth interface between VisSim and Maple.

The new add-on ‘Knobs and Gauges’ block set lets the user specify various blocks to give high quality graphical behaviour of interactive gauges, meters, dials, switches and knobs. This allows the user to create a ‘dashboard’ face plate to drive and monitor your VisSim model.

VisSim 6.0 brings an improved user interface. The addition of the VisSim Tutor allows the user to annotate a VisSim diagram with interactive help balloons so that the user can read and understand it better.

The new VisSim Diagram Explorer Window now allows the user to explore the VisSim menu hierarchy. This makes it very convenient to insert blocks from deeply nested menu trees.

Simulation engine enhancements include:

• Subsystem Superclocking, which allows all blocks within a compound block to run at a user defined rate faster than the overall sym rate. It allows for containment of high frequency components, iterating through matrices, or modelling of partial differential equations.
• Two new adaptive integration methods for solving stiff systems.
• A real time scale factor which allows the user to run real time simulations at multiples or fractions of real time.
• Auto check pointing lets the user automatically save diagram state to a file name with a time stamp suffix. The file contains the current state of all variables in the diagram at that point of the simulation. This is useful for operator training, allowing the operator to go back in time and re-simulate questionable decisions.
