Dymola is a physical modelling and simulation tool, used for model based design of complex systems.
Dymola uses the Modelica modelling language to define models and provides the user with open access to the language. This means that you are free to create your own model libraries or extend from the existing Modelica libraries to accelerate development times, reduce maintenance efforts and improve the level of reuse across projects.
A portfolio of multi-domain libraries covering the mechanical, electrical, control, thermal, pneumatic, hydraulic, powertrain, thermodynamics, vehicle dynamics, air-conditioning domains can be coupled together to form a single complete model of the system. Dymola is used by companies operating in many industries including automotive, aerospace, architecture, motorsport, energy and high tech.
Dymola supports the FMI Standard for the import and export of models. It supports FMI 1.0 and 2.0 for both model exchange and co-simulation. In addition, Dymola supports real-time simulation on a wide range of HiL platforms.

Back To The Future Flying DeLorean
We are always looking for interesting combinations of libraries and good demonstrations of novel systems, we have many useful examples within our libraries demonstrating that. Such as the use of the hydrogen library with VeSyMA, as described in Theo’s blog post about a hydrogen bus model; or lots of...
What are Your Library’s Dependencies?
The recent Dymola 2023x Refresh 1 release provides a number of new features and improvements. I’m going to talk about a new built-in function which you may have missed, getDependentLibraries, that I’ve been using to check our libraries’ dependencies. Modelica Library Dependencies There are many Modelica Libraries available, covering...
A rain water harvesting example
Water is scarce in many parts of the world, one way to reduce water usage is to collect the rain water runoff, typically from your roof. This rain water collecting is rain water harvesting and in this post a simple rain water harvesting model is created to estimate the...
Using physical connectors with an FMU
This post has a look at how to interface with FMU blocks that make use of physical connectors. In this blog a simple electrical circuit is split into two FMUs that interface with electrical connectors. What is a physical connector? A connector that could be found on a physical...
Use of the Model Management Library
With the installation of Dymola there is the Model Management library, which allows users to be able to gain data about models and even create and modify models. This can be a very powerful and useful tool, if used correctly. This post will go through a couple of examples...

Demo Download
A demonstration version of Dymola is available for download. It gives you access to the core functionality of Dymola and the ability to build and simulate simple Modelica models but it doesn’t include access to any of the optional features or Modelica libraries. Full on-line documentation is available from within Dymola and contains a Getting Started guide and Reference Manuals.
There are some restrictions in the demo version and these can be overcome by applying for an evaluation license:
- Complex models cannot be simulated
- Only one external function call is allowed
The demo version can be downloaded using the button below and completing the online form.
The following documents are also available for download:
Any questions or queries, or if you’d like to apply for an evaluation license, please get in touch.
