OpenModelica is an open-source Modelica-based modeling, compilation, and simulation environment for industrial and academic use. It includes the OMCompiler, the OMEdit graphical interface, and OMSimulator for FMI and SSP-based co-simulation.
Use cases
- simulate physical systems described in Modelica
- compile and run Modelica models
- perform FMI co-simulation of coupled models
- teach equation-based object-oriented modeling
- optimize and run sensitivity analysis on models
- develop Modelica-compliant libraries
When to choose
- you need a free, open-source Modelica modeling and simulation tool
- you want FMI/SSP co-simulation support
- you need both a GUI (OMEdit) and scripting APIs for simulation workflows
- you are doing academic research or teaching in system modeling
When to avoid
- you need commercial support or certified toolchains for safety-critical workflows
- you only need lightweight block-diagram simulation without the Modelica language
- you require a purely web-based modeling environment
