Hydraulic actuators, battery stacks, biochemical systems and disease propagation are but a few things that now can be modelled more easily, thanks to a number of libraries and a library store that Wolfram Research has created for a new edition of its SystemModeler software package.
Wolfram SystemModeler 4.0, also comes with improved interfaces for building models, as well as better documentation and integration with Wolfram’s flagship Mathematica mathematical computing software.
SystemModeler provides a way for engineers and designers to create models of complex systems, as well as to simulate how such systems could run, using time-lapse visualisations. Wolfram obtained the SystemModeler code from MathCore Engineering, a company it purchased in 2011.
The company has since been building up the libraries to cover the many potential engineering and scientific uses for the software. A library provides the functionality for describing specific physical or mathematical properties, so they can be rendered correctly in a visual model.
In the field of electronics for instance, the updated software now has libraries for modelling digital electronics in the VHDL standard, for modelling multiphase electrical machines, and for the approximate modelling of large analogue circuits.
Wolfram has also opened an app store of sorts, an online repository of paid and free third-party libraries for SystemModeler. Each library has been tested by Wolfram.
At the SystemModeler Library Store, you will find a $995 (€740) library for modelling hydraulics in pumps, motors, actuators, cylinders, valves and other components. Another library, priced at $7,185 (€5,341), can aid in the design of automotive cooling systems.
SystemModeler is one of a number of software programs designed to help engineers visually model complex systems. Others include Maplesoft’s MapleSim and Simulink, from MathWorks.
