OpenModelica is an open-source Modelica-based cyber-physical mathematical modeling, architectural description, simulation and optimization environment intended for industrial and academic usage. Its long-term development is supported by a non-profit organization – the Open Source Modelica Consortium (OSMC).

See further below regarding Call for Presentations for the OpenModelica workshop February 2, 2021, MODPROD workshop February 3-4. (Model-Based Cyber-Physical Product Development) The OpenModelica 1.16.0 Final release October 24, 2020, includes more than 300 improvements and fixes compared to the previous 1.14.0 release. It is available here: (Download Linux<https://openmodelica.org/download/download-linux>, Mac<https://openmodelica.org/download/download-mac>, Windows<https://openmodelica.org/download/download-windows>. Report bugs in Trac<https://trac.openmodelica.org/OpenModelica/newticket>.) . The most recent documentation is here<https://www.openmodelica.org/doc/OpenModelicaUsersGuide/latest/>. This release includes a further improved new OpenModelica Compiler frontend, that was first available in the previous 1.14.0 release, with an average factor 10-20 speed improvement. OpenModelica 1.16.0 includes basic replaceable class support in the GUI, as well as a lot of new functionality and bug fixes. This is a big step forward since replaceable GUI has been under part-time development for 3 years and required a completely new frontend and many OMEdit enhancements. The support of replaceable classes in OMEdit is currently limited to the case in which a replaceable class is redeclared, without specific parameter modifiers. This is enough, e.g., to use Modelica.Fluid and Modelica.Media. Please note that this feature is optional in this version of OMEdit, so it must be activated with Tools ->Options ->General -> Enable replaceable support. The handling of redeclared class parameters is planned to be added in the next release, 1.17.0, due end of January 2020 OpenModelica Compiler enhancements: The new compiler frontend has been further improved, with enhanced support of records and arrays. The new front-end can now handle 100% of the Modelica Standard Library 3.2.3 models. Improvements to the compiler back-end and run-time: new minimal tearing option --minimalTearing to disable tearing except for discrete variables, improved symbolic Jacobian evaluation option --simJacConstantSplit reuses constant part of the Jacobian, improvements to dynamic state selection and common subexpression elimination, new ASCC algorithm replaces and improves resolveLoops algorithm, allowing to detect high-index problems with indirect structural state constraints, e.g. in three-phase AC circuits, homotopy operator now used on first try by default, linearized model export also available in Matlab, Python, and Julia with --linearizationDumpLanguage option, Better support for models with records, CVODE solver from SUNDIALS added; – 2 methods available: BDF (stiff) and Adams-Moulton (non-stiff). Also, it is now possible to build a version of OMC with parallel Jacobian evaluation using OpenMP. FMI and SSP Support: Many FMI export bug fixes have been made, and improvements to the usability of OMC-generated FMUs. FMI/CoSimulation 2.0 now includes CVODE solvers (previously only fixed-step forward Euler) and customization via simulation flags. OMSimulator now supports the SSP 1.0 standard. OMSimulator GUI iimprovements: text editing of SSP models, undo/redo, delete components, etc. Other enhancements: A special version of OMC available to Consortium members can now handle encrypted libraries. Enhanced OM Debugger that can trace (and plot) which variables and equations influence a variable., A full-fledged Modelica package manager<https://openmodelica.org/doc/OpenModelicaUsersGuide/latest/packagemanager.html> is also included in OpenModelica 1.16.0, currently only with a command line interface; integration in the GUI is planned in future releases. Support for single- and multi-parameter sensitivity analysis.
