Control Engineering Softwares

Modelica, Modeling of Complex Physical Systems. The object-oriented modeling language Modelica is designed to allow convenient, component-oriented modeling of complex physical systems, e.g., systems containing mechanical, electrical, electronic, hydraulic, thermal, control, electric power or process-oriented subcomponents. The free Modelica language, free Modelica libraries and Modelica simulation tools are available, ready-to-use and have been utilized in demanding industrial applications, including hardware-in-the-loop simulations. The development and promotion of Modelica is organized by the non-profit Modelica Association. More, see overview article ….

OOfelie Object Oriented Finite Elements Led by Interactive Execution. This project is the result of a collaboration between the Computational Mechanics Group of INTEC and the Laboratoire de Techniques Aéronautiques et Spatiales, University of Liege, Belgium. The objective of this work is to define the architecture of a new finite element program using the C++ programming language. The program is built around an interpreter, which allows the user to define interactively either data as well as algorithms. The program may thus be very easily configured to new computational strategies. See also the non official site.

Scientific Computing in Python

SciPy an open source library of scientific tools for Python. SciPy supplements the Numeric module, gathering a variety of high level science and engineering modules together as a single package. Within SciPy are modules for graphics and plotting, optimization, integration, special functions, signal and image processing, genetic algorithms, ODE solvers, and others. There is also an experimental “compiler” that takes a Numeric array expression in Python and compiles it to C++ code on the fly.

Scientific Python Konrad Hinsen’s Scientific Python is a module library for scientific computing. In this collection you will find modules that cover basic geometry (vectors, tensors, transformations, vector and tensor fields), quaternions, automatic derivatives, (linear) interpolation, polynomials, elementary statistics, nonlinear least-squares fits, unit calculations and conversions, Fortran-compatible text formatting, 3D visualization via VRML, two Tk widgets for simple line plots and 3D wireframe models. Scientific Python also contains Python interfaces to the netCDF library (implementing a portable binary format for large arrays) and the Message Passing Interface, the most widely used communications library for parallel computers. Konrad Hinsen’s course, Python for Scientists shows how to use scientific python
