ModelicaOpenModelica

ModelicaOpenModelica is a term used to describe the use of the OpenModelica platform for working with models written in the Modelica language. It denotes the combination of the Modelica modeling language, which supports multi-domain, component-based modeling, with the OpenModelica environment that provides tools for authoring, simulating and analyzing Modelica models.

Modelica is an object-oriented, declarative language designed for representing complex physical systems. It emphasizes describing the relationships between components rather than prescribing procedural steps. Modelica supports acausal equations, hierarchical model composition, and libraries for domains such as mechanical, electrical, thermal, and control systems. The Modelica Standard Library and third-party libraries provide building blocks for a wide range of applications, enabling reuse and collaboration across research and industry.

OpenModelica is an open-source platform that implements the Modelica language and provides an end-to-end toolchain for modeling and simulation. It includes an integrated development environment (OMEdit), a compiler (OMCompiler), and runtime components. The platform supports co-simulation through the Functional Mock-up Interface (FMI), allows model experimentation, and facilitates plotting and analysis. It runs on multiple operating systems and aims to be extensible through plugins and scripting, with interfaces to languages such as Python for automation and data processing.

Together, ModelicaOpenModelica supports education, research, and early-stage development by offering an accessible, community-driven way to build and test Modelica models. It is commonly used for teaching Modelica concepts, validating models against physical phenomena, and prototyping multi-domain systems.
