OpenModelica [1] [2] is a free and open source environment based on the Modelica modeling language for modeling, simulating, optimizing and analyzing complex dynamic systems. This software is actively developed by Open Source Modelica Consortium, [3] a non-profit, non-governmental organization. The Open Source Modelica Consortium is run as a project of RISE SICS East AB in collaboration with Linköping University.
OpenModelica is used in academic and industrial environments. Industrial applications include the use of OpenModelica along with proprietary software in the fields of power plant optimization, [4] automotive [5] and water treatment. [6]
OpenModelica Compiler (OMC) is a Modelica compiler, translating Modelica to C code, with a symbol table containing definitions of classes, functions, and variables. Such definitions can be predefined, user-defined, or obtained from libraries. The compiler also includes a Modelica interpreter for interactive usage and constant expression evaluation. The subsystem also includes facilities for building simulation executables linked with selected numerical ODE or DAE solvers. The OMC is written in MetaModelica, [7] a unified equation-based semantical and mathematical modeling language and is bootstrapped.
OpenModelica Connection Editor [8] [9] is an open source graphical user interface for creating, editing and simulating Modelica models in textual and graphical modes. OMEdit communicates with OMC through an interactive API, requests model information and creates models/connection diagrams based on the Modelica annotations. The implementation is based on C++ and the Qt library.
OpenModelica Shell (OMShell) is an interactive command-line interface that parses and interprets commands and Modelica expressions for evaluation, simulation, plotting, etc. The session handler also contains simple history facilities, and completion of file names and certain identifiers in commands.
OpenModelica Notebook (OMNotebook), is a light-weight Mathematica-style editor for Modelica that implements interactive WYSIWYG realization of Literate Programming, a form of programming where programs are integrated with documentation in the same document.
OMNotebook is primarily used for teaching and allows to mix hierarchically structured text with cells containing Modelica models and expressions. These can be evaluated, simulated and plotted with the results displayed directly in the OMNotebook.
OMPython is a Python interface enabling users to access the modeling and simulation capabilities of OpenModelica from Python. It uses CORBA (omniORB) or ZEROMQ to communicate with the OpenModelica scripting API.
OMMatlab is a Matlab interface that provides access the modeling and simulation capabilities of OpenModelica from matlab. It uses ZEROMQ to communicate with the OpenModelica compiler API.
MDT is an Eclipse plugin that integrates the OpenModelica compiler with Eclipse. It provides an editor for advanced text based model editing with code assistance. MDT interacts with the OpenModelica Compiler through an existing CORBA based API and is used primarily in the development of the OpenModelica compiler.
Wolfram Mathematica is a software system with built-in libraries for several areas of technical computing that allow machine learning, statistics, symbolic computation, data manipulation, network analysis, time series analysis, NLP, optimization, plotting functions and various types of data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other programming languages. It was conceived by Stephen Wolfram, and is developed by Wolfram Research of Champaign, Illinois. The Wolfram Language is the programming language used in Mathematica. Mathematica 1.0 was released on June 23, 1988 in Champaign, Illinois and Santa Clara, California.
Scilab is a free and open-source, cross-platform numerical computational package and a high-level, numerically oriented programming language. It can be used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, numerical optimization, and modeling, simulation of explicit and implicit dynamical systems and symbolic manipulations.
An interface description language or interface definition language (IDL) is a generic term for a language that lets a program or object written in one language communicate with another program written in an unknown language. IDLs are usually used to describe data types and interfaces in a language-independent way, for example, between those written in C++ and those written in Java.
In software engineering, the terms frontend and backend refer to the separation of concerns between the presentation layer (frontend), and the data access layer (backend) of a piece of software, or the physical infrastructure or hardware. In the client–server model, the client is usually considered the frontend and the server is usually considered the backend, even when some presentation work is actually done on the server itself.
In computing, a visual programming language, also known as diagrammatic programming, graphical programming or block coding, is a programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation. For example, many VPLs are based on the idea of "boxes and arrows", where boxes or other screen objects are treated as entities, connected by arrows, lines or arcs which represent relations.

Modelica is an object-oriented, declarative, multi-domain modeling language for component-oriented modeling of complex systems, e.g., systems containing mechanical, electrical, electronic, hydraulic, thermal, control, electric power or process-oriented subcomponents. The free Modelica language is developed by the non-profit Modelica Association. The Modelica Association also develops the free Modelica Standard Library that contains about 1400 generic model components and 1200 functions in various domains, as of version 4.0.0.
Hopsan is a free simulation environment for fluid and mechatronic systems, developed at Linköping University. Although originally developed for simulation of fluid power systems, it has also been adopted for other domains such as electric power, flight dynamics, and vehicle dynamics. It uses bi-directional delay lines to connect different components.

EMSO simulator is an equation-oriented process simulator with a graphical interface for modeling complex dynamic or steady-state processes. It is CAPE-OPEN compliant. EMSO stands for Environment for Modeling, Simulation, and Optimization. The ALSOC Project - a Portuguese acronym for Free Environment for Simulation, Optimization and Control of Processes -, which is based at the UFRGS, develops, maintains and distributes this object-oriented software. Pre-built models are available in the EMSO Modeling Library (EML). New models can be written in the EMSO modeling language or a user can embed models coded in C, C++ or Fortran into the simulation environment.
