The Dymola solver implements events that may be in a model to allow it to solve in an accurate way. This post has a closer look at how this is implemented. What is an event? When discrete behaviour occurs in a model an event is generated, or to say...

It’s often tempting with systems modelling to want to reach a solution as quickly as possible, effectively “throwing” all the components together, parameterising and simulating the scenario of interest and getting the results we need. However, doing this is generally more time consuming than taking a steadier approach. The...
Testing of system models coupled to autonomous and human operators is something we do a lot of at Claytex. The system models need to be both representative of the characteristics and behaviour of the real world components, in addition to being fast and robust enough to simulate with minimal...
Dassault Systemes have announced the availability of a new version of Dymola. The key highlights of Dymola 2023 release are: Additions and improvements in Dymola Better presentation of timers Improved search of records Model metadata support Support of Markdown for documentation Steady state solver interface Max run time per simulation Nonlinear solver statistics...
This blog post will introduce newcomers to the difference between using co-simulation FMUs (Functional Mock-up Units) and Model Exchange FMUs. FMI – Functional Mock-up Interface FMU – Functional Mock-up Unit (a model, for example, which has been wrapped within the Functional Mock-up Interface). For more information on FMI please...
eMobility will only become a reality with advanced simulation tools. Mike Dempsey, Managing Director of Claytex As the world grapples with the challenge of averting permanent climate change, eMobility is a topic that has risen from the fringes of academic research to mainstream technological focus. One could be forgiven...
In our most recent Dymola release, we have introduced the UAVDynamics library. It can model the hardware and flight physics of a drone, but it also comes with a new capability: linking up to an intelligent drone piloting software that will allow it to fly real virtual missions. Meet...
When debugging a model, a de-cluttered messages log window makes it easier to identify what the important/critical problems are that Dymola has found with the model. How can we de-clutter a log window though without loosing valuable information Dymola tells us about the model? There will be text in...
In Dymola 2022x a new keyboard shortcut to setting SI units in the text editor has been introduced. This post has a look at this new method. Unit checking Units are extremely important; just ask a scientist of the NASA’s Mars Climate Orbiter, that after travelling 300 million km...
When people ask me “What are the advantages of using Dymola for physical modelling over your more traditional simulation environments”, amongst other things such as automated code optimisation, I respond “It is the openness of models and the ability this gives to be able to familiarise ourselves with the...
