This is a listing of builtin Modelica functions, miscellaneous Modelica libraries stored in a git repository. There is also documentation for OpenModelica-specific scripting.
Note that not all libraries are supported or have been tested. Feel free to add bug reports either to OpenModelica (for compiler bugs) or to the GitHub projects for enhancements or bugs in the libraries. Older libraries may contain broken links and images (only libraries with modelica:// links produce good documentation). The Modelica Standard Library is the best supported package in OpenModelica.
