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.
