About

This is a community package of OpenModelica, maintained independently and unaffiliated with the Open Source Modelica Consortium. It downloads a bundle of official stable OpenModelica binaries, Qt WebEngine and their runtime libraries from rhgKc2yp/OMEdit-release. The upstream binaries are not modified; the bundle's source manifest records their origins and hashes.

OpenModelica is an open-source Modelica-based modeling and simulation environment for industrial and academic use. OMEdit provides a graphical interface for creating models, connecting components, running simulations and plotting results.

To use the Algorithmic Debugger, enable ptrace access by running flatpak override --user --allow=devel org.openmodelica.OpenModelica and restart OpenModelica. This permission is not required for normal use.

  • Create equation-based physical models graphically or as Modelica source.
  • Compile and simulate models with the toolchain contained in the sandbox.
  • Plot simulation variables and inspect generated results.
  • Use the bundled offline cache of the Modelica Standard Library.

Permissions: network access is used for Modelica library downloads, documentation and release information. GPU access is used for accelerated Qt rendering. Downloaded libraries are persisted in OpenModelica's private .openmodelica directory; this package does not grant access to your home directory. Open and save files elsewhere with the desktop file chooser.

OpenModelica simulations generate and compile native code. This package therefore uses the KDE SDK runtime, whose GCC toolchain remains inside the Flatpak sandbox.
