One of the biggest challenges for autonomous vehicles (AV) is how to argue their safety case. The first step towards a state of informed safety is establishing the capability of an automated driving system (ADS) by defining its operational design domain (ODD). What is an ODD? “ODD is an...
When creating models it can be difficult to work out the best route to getting the best result most efficiently and with the best usability. Modelica and all the Claytex Libraries use a system of inheritance as described in the 8th Dymola Basics post. This means that extending from...
Two weeks ago, the Claytex tech blog considered the role simulation must play in modern automotive development in a conceptual way. But what does that look like in context? How can VeSyMA be integrated into OEM workflows? Existing structures need updating for modern vehicles First, we must understand the...
This post looks at a simple way to check that derivatives of a function are correct and in the process explores some of the different plotting features of Dymola. When should derivatives be checked? Most of the time it is best to let Dymola calculate derivatives (see automatically-getting-derivatives-of-a-function-in-dymola). However...
As vehicles are getting more complex as integrated mechatronic systems, approaches which are cross-disciplinary using simulation are now vital. Development processes need to be able to capture and understand all the permutations of each design change or choice, which cannot be easily discretised into singular studies, whether physical or...
Dymola and Modelica make the distribution and deployment of simulation models a relatively simple process. There is often some reservation by model developers concerning how much of a model they may want to reveal to the end users. There are various reasons the developer may want to conceal the...
The COVID-19 pandemic has seen demand for simulation go stratospheric, says Claytex’s Managing Director Mike Dempsey. “People are turning to simulation more than they ever have done. It’s not as easy to go and take a car out and do some tests on the public road or around a...
In my last blog post, Migration to Newer Library Versions, I looked at using conversion scripts to migrate your library to newer versions of other libraries used. But how are these conversion scripts created? In this blog post I’m going to go through an approach you can use to...
Two of the many new features in Dymola 2022 – “Max run time” and “Stop when steady state is reached”
In Dymola 2022 there are a number of new features ranging from simulation stop time auto adjustment all the way to the implementation of cross platform FMUs, the latter will be a feature of my colleague’s future blog post. In this post we will focus on two new features...
This blog post seeks to raise awareness of how objects such as visualisers/visualizers reference global settings that can be enabled and adjusted from within the Animation Setup and World objects within Dymola. Often we want to be able to visualise the application of forces and torques to better understand...
