OpenModelica 1.19.0 Release OpenModelica is an open-source Modelica-based cyber-physical mathematical modeling, architectural description, simulation, digital twin building, 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).

(If you do not wish to receive these messages, see the end of this email). We are happy to announce that version 1.19.0 of OpenModelica has just been released. The main new feature of this release is much improved handling of system libraries. The package manager<https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fopenmodelica.org%2Fdoc%2FOpenModelicaUsersGuide%2F1.19%2Fpackagemanager.html&data=05%7C01%7Cpeter.fritzson%40liu.se%7C432bf1ed8f12444aa16d08da45bd6e55%7C913f18ec7f264c5fa816784fe9a58edd%7C0%7C0%7C637898977152672444%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=faLU10TKE9CjUTx3MafGTKK%2B1FiE7br02IVs96tQ67I%3D&reserved=0> is now fully integrated with the OMEdit GUI, which makes it possible to install and update released open-source Modelica libraries and their dependencies with a few clicks<https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fopenmodelica.org%2Fdoc%2FOpenModelicaUsersGuide%2F1.19%2Fomedit.html%23install-library&data=05%7C01%7Cpeter.fritzson%40liu.se%7C432bf1ed8f12444aa16d08da45bd6e55%7C913f18ec7f264c5fa816784fe9a58edd%7C0%7C0%7C637898977152672444%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=%2F3xSacJ%2Bw7vI8axqlg59irSrtDzBjjcbpqjswBsOo6M%3D&reserved=0>. OpenModelica now also supports conversion scripts, to upgrade existing libraries to newer versions of libraries they depend on, if they are not backwards-compatible but provide automatic conversion scripts. Just right-click on the package in the Libraries Browser of OMEdit and select "Convert to newer version of used libraries". This allows to manage the transition of existing models and libraries to version 4.0.0 of the Modelica Standard Library using OpenModelica. In general, package version management has improved considerably, compared to previous versions of the software. For example, if you open an old library using Modelica 3.2.3 in OMEdit 1.19.0, but already have Modelica 4.0.0 loaded in the Libraries Browser, a pop-up window offers you the option to unload Modelica 4.0.0 and load your old library with its proper dependencies. Previously, you got some warning messages about conflicting library versions and basically nothing worked at all. Getting all these features to work seamlessly in all cases across different operating systems and user configurations took longer than expected, delaying the release by a few months. Unfortunately we could not release 1.19.0 without ironing out all he problems that popped up with library management, otherwise we could have caused more than a headache; we think the final result is good and well worth the waiting. Please provide feedback to further improve it. The level of support of open-source Modelica libraries in version 1.19.0 has increased significantly<https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flibraries.openmodelica.org%2Fbranches%2Foverview.html&data=05%7C01%7Cpeter.fritzson%40liu.se%7C432bf1ed8f12444aa16d08da45bd6e55%7C913f18ec7f264c5fa816784fe9a58edd%7C0%7C0%7C637898977152672444%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=rUp52uTZGSw4RaHMDslRmQnQ3COYmTz5sE45jp3%2F7Ps%3D&reserved=0>, also thanks to an OSMC initiative sponsored by LBL labs to improve the support of the Buildings library. The new frontend has now completely superseded the old one, guaranteeing a uniformly superior performance in term of compilation speed and libraary coverage. Some runtime issues that affected the simulation results of clocked models, introduced in Modelica 4.0.0, have been resolved, so that clocked models now work correctly. This means that Modelica 4.0.0 is now supported without compromises by OpenModelica.

If you use OpenModelica for your daily work, we definitely recommend to upgrade to this new release for a much improved user experience. Many thanks to all the developers who worked hard during the last months to achieve this new milestone!
