New driver models are included in the recent 2025.1 release of the VeSyMA – Motorsport library, which accompanies the new Dymola 2025x Refresh 1 release. These new motorsports driver models are streamlined versions of existing driver models in the VeSyMA – Suspensions library that are better suited to motorsports...
Python is a versatile language that can be used as both a scripting and general programming code. Modelica, on the other hand, is a more niche product leveraged (often via Dymola) to solve complex multi physics engineering problems. The two languages are often deployed together to good effect. Using...
We wrote about the installation of Dymola on Linux earlier on in 2021. This blog post looks at giving a quick guide to installation of Dymola on Windows. The Dymola installer is the same regardless of whether you have a Dymola licence or not. It is the licence that...
For the second season in a row, Claytex has taken a (rather long) field trip up to Scotland. This season we moved to a different site, again in the foothills of the Cairngorms, near Pitlochry. But this time, we were able to organise a site with a lot more...

A Dymola license can in some cases be used to run an exported model, this is referred to as the Dymola Runtime concept and is examined in this post. The information regarding setting up the Runtime license was obtained from the Dymola User Manual. When would the Dymola Runtime...
Modelica does not require causality to be assigned in equations. This means that a Modelica solver, such as Dymola, must be able to solve an equation independent on which of the variables are inputs and which are unknowns. To test this in Dymola an example based on flying a...
