Multi-Engineering Moldeling and Simulation software based on Modelica and FMI

Dymola, Dynamic Modeling Laboratory, is a complete tool for modeling and simulation of integrated and complex systems for use within automotive, aerospace, robotics, process and other applications.


Rapidly solve complex multi-disciplinary systems modeling and analysis problems, using Dymola’s best-in-class Modelica and simulation technology. Dymola is a complete environment for model creation, testing, simulation and post-processing.


  • Multi-engineering – Dymola has unique multi-engineering capabilities which means that models can consist of components from many engineering domains
  • Intuitive modeling – Dymola’s graphical editor and the multi-engineering libraries make modeling easy.
  • Open and flexible – The Dymola environment is completely open in contrast to many modeling tools that have a fixed set of component models and proprietary methods for introducing new components.
  • Interoperablity Options – Dymola offers a broad variety of interoperability options. Profit from the full support of the FMI standard, Python scripting or use the Simulink interface.
  • Symbolic Manipulation – Dymola has unique and outstanding performance for solving differential algebraic equations (DAE).


Key Benefits


 Compatible model libraries for many engineering fields enable high-fidelity modeling of complex integrated systems.


 A powerful, object-oriented and formally defined modeling language

Free and commercial libraries

User can easily build own or adapt existing components to match unique needs. Comprehensive portfolio of model libraries


Acausal, equation-oriented models allow a component to be used in different contexts and a model to be used for different studies

Symbolic equation processing

Relieves the user from converting equations to assignment statements or block diagrams. Simulations are more efficient and robust

Hardware-in-the-Loop Simulation (HILS)

Real-time simulation on dSPACE and xPC

Powerful interoperability options

With full FMI support and interfaces to Python, the SIMULIA tools Abaqus and iSight as well as Simulink


Real-time 3D animation and import of CAD files for visualization

Model Creation

Dymola allows you to capture the parameters of existing components to create new models. This encourages the creation of specialised component libraries that can be used in subsequent designs.

Improved use of display units for parameters and variables in the graphical editor and in plots improves readability and reduces model ambiguity.


To further support the simulation of hard thermo-fluid problems, Dymola has more robust and efficient handling of models with nonlinear equation systems through improved handling of initial values. Improved diagnostics at compilation and runtime helps find difficult numeric problems, and intermediate values can be checked during debugging.

Optimised handling of parameters helps minimise code generation for large tables of data, leading to faster model translation, simulation and post-processing

Modelica Libraries

Modelica tools are domain-agnostic, meaning that they process equations in order to generate efficient simulation code. Domain knowledge is packed in Modelica libraries, designed to handle a variety of applications from mechanical, electrical, and thermo-fluid domains.

Developed by domain specialists, these libraries are used in conjunction with Dymola or 3DEXPERIENCE Dymola Behavior Modeling to quickly and easily model and simulate the behavior of complex systems. These span across multiple engineering disciplines, including automotive, aerospace & defence, energy, processes & utilities and industrial equipment.
