Modelica
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. Characteristics While Modelica resembles object-oriented programming languages, such as C++ or Java, it differs in two important respects. First, Modelica is a modeling language rather than a conventional ''programming'' language. Modelica classes are not compiled in the usual sense, but they are translated into objects which are then exercised by a simulation engine. The simulation engine is not specified by the language, although certain required capab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SimulationX
SimulationX is a CAE software application running on Microsoft Windows for the physical simulation of technical systems. It is developed and sold by ESI Group. History In the mid 1980s, VEB Mikromat in Dresden ( Germany) developed a program for DOS to design controlled feed axis systems and to perform hydraulic calculations. In 1993, ITI GmbH, founded by former Mikromat employees in 1990, introduced a simulation tool for Microsoft Windows designed for dynamic calculations of drive systems: ITI-SIM 1. With the release of ITI-SIM 2 in 1995, the software also allowed for fluid simulations. In 2002, the newly developed application SimulationX, based on the object-oriented description language Modelica, was introduced to the market. By the year 2007, ITI-SIM (then in version 3.8) had been completely replaced by SimulationX. Since the beginning of 2016, ITI belongs to the ESI Group and now operates under the name ESI ITI GmbH.

MapleSim
MapleSim is a Modelica-based, multi-domain modeling and simulation tool developed by Maplesoft. MapleSim generates model equations, runs simulations, and performs analyses using the symbolic and numeric mathematical engine of Maple. Models are created by dragging-and-dropping components from a library into a central workspace, resulting in a model that represents the physical system in a graphical form. Maplesoft began development of MapleSim partly in response to a request from Toyota to produce physical modeling tools to aid in their new model-based development process. The MapleSim library includes many components that can be connected together to model a system. These components are from areas of science and engineering such as electrical, mechanical, and thermal engineering fields. MapleSim also includes traditional signal flow components that can be combined with other physical components in the workspace. Thus, MapleSim is able to combine causal modeling methods with aca ...

EcosimPro
EcosimPro is a simulation tool developed by Empresarios Agrupados A.I.E for modelling simple and complex physical processes that can be expressed in terms of Differential algebraic equations or Ordinary differential equations and Discrete event simulation. The application runs on the various Microsoft Windows platforms and uses its own graphic environment for model design. The modelling of physical components is based on the EcosimPro language (EL) which is very similar to other conventional Object-oriented programming languages but is powerful enough to model continuous and discrete processes. This tool employs a set of libraries containing various types of components (mechanical, electrical, pneumatic, hydraulic, etc.) that can be reused to model any type of system. It is used within ESA for propulsion systems analysis and is the recommended ESA analysis tool for ECLS systems. Origins The EcosimPro Tool Project began in 1989 with funds from the European Space Agency (E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dassault Systèmes
Dassault Systèmes SE () (abbreviated 3DS) is a French software corporation which develops software for 3D product design, simulation, manufacturing and other 3D related products. Founded in 1981, it is headquartered in Vélizy-Villacoublay, France, and has around 20,000 employees in 140 countries. History 1980s Dassault Systèmes (3DS) grew out of the aerospace industry’s search for more sophisticated drafting tools to streamline the development process and aid in the increasing complexity of aviation design. Dassault Systemes spun out in 1981 (as part of Dassault Group.) to develop and market Dassault's 3D surface design software CATI, later renamed CATIA. That same year, 3DS signed a sales and marketing agreement with IBM, allowing IBM to resell the CATIA CAD software. 1990s In the 1990s, 3DS’ software was used to develop seven out of every ten new airplanes and four out of every ten new cars worldwide. Major players in the aviation and automotive industries, inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apache Subversion
Apache Subversion (often abbreviated SVN, after its command name ''svn'') is a software versioning and revision control system distributed as open source under the Apache License. Software developers use Subversion to maintain current and historical versions of files such as source code, web pages, and documentation. Its goal is to be a mostly compatible successor to the widely used Concurrent Versions System (CVS). The open source community has used Subversion widely: for example, in projects such as Apache Software Foundation, Free Pascal, FreeBSD, SourceForge, and from 2006 to 2019, GCC. CodePlex was previously a common host for Subversion repositories. Subversion was created by CollabNet Inc. in 2000, and is now a top-level Apache project being built and used by a global community of contributors. History CollabNet founded the Subversion project in 2000 as an effort to write an open-source version-control system which operated much like CVS but which fixed the bugs a ...

AMESim
Simcenter Amesim is a commercial simulation software for the modeling and analysis of multi-domain systems. It is part of systems engineering domain and falls into the mechatronic engineering field. The software package is a suite of tools used to model, analyze and predict the performance of mechatronics systems. Models are described using nonlinear time-dependent analytical equations that represent the system's hydraulic, pneumatic, thermal, electric or mechanical behavior. Compared to 3D CAE modeling this approach gives the capability to simulate the behavior of systems before detailed CAD geometry is available, hence it is used earlier in the system design cycle or V-Model. To create a simulation model for a system, a set of libraries is used. These contain pre-defined components for different physical domains. The icons in the system have to be connected and for this purpose each icon has ports, which have several inputs and outputs. Causality is enforced by linking the inpu ...

Pascal (programming Language)
Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named in honour of the French mathematician, philosopher and physicist Blaise Pascal. Pascal was developed on the pattern of the ALGOL 60 language. Wirth was involved in the process to improve the language as part of the ALGOL X efforts and proposed a version named ALGOL W. This was not accepted, and the ALGOL X process bogged down. In 1968, Wirth decided to abandon the ALGOL X process and further improve ALGOL W, releasing this as Pascal in 1970. On top of ALGOL's scalars and arrays, Pascal enables defining complex datatypes and building dynamic and recursive data structures such as lists, trees and graphs. Pascal has strong typing on all objects, which means that one type of data cannot be converted to or interpreted as another without explicit conv ...
