The OpenModelica Integrated Modeling, Simulation, and Optimization Environment

OpenModelica is currently the most complete opensource Modelica-and FMI-based modeling, simulation, optimization, and model-based development environment.Moreover, the OpenModelica environment provides a number of facilities such as debugging; optimization; visualization and 3D animation; web-based model editing and simulation; scripting from Modelica, Python, Julia, and Matlab; efficient simulation and co-simulation of FMI-based models; compilation for embedded systems; Modelica-UML integration; requirement verification; and generation of parallel code for multi-ore architectures.The environment is based on Modelica and uses an extended version of Modelica for its implementation.This overview paper intends to give an up-to-date brief description of the capabilities of the system, and the main vision behind its development.
