Considerations on ICE ancillary and sub-system electrification
With the ever increasing electrification of ICE (Internal Combustion Engine) ancillaries and sub-systems, holistic approaches to quantification of benefits is essential. Historically and even in present day, vehicle design is still siloed to an extent. Each department is concerned with the design of their own systems using boundary conditions...
Using Dymola to understand the 2018 Indy 500
To the uninitiated, the Indy 500 seems like a simple event. 200 laps (500 miles) around the Indianapolis Motor Speedway, a 2.5 mile long banked oval circuit using single-seater, open wheel IndyCars. Sounds simple enough, doesn’t it? Well… it isn’t. As with any top level Motorsport, drivers straddle the...
Result plotting made easier
I am always of the opinion that a large amount of small tweaks to the way we work every day will not only make our modelling more efficient, but also more enjoyable. So, here’s another relatively small tip that will speed up your modelling available in Dymola 2020 onwards....
Preserving the Dymola Translation Log
Why save the translation log? Running simulations in batches can be useful for a number of reasons. Many times, the most convenient way to do that is to create a function that simulates a few models consecutively. One good example of a use case is when running a complete...
Dangerous Trailer Dynamics
With summer time approaching numbers of caravans and trailers on the roads skyrockets with people heading off for their holidays. Invariably this means, up and down the country, there are incidents involving trailers and caravans, predominantly on fast paced roads. So what makes a safe car and trailer combination,...
The “Resources” folder
It is good coding practice to store files used by a library in a Resources folder. This post looks at the typical Resources folder structure, the advantages of using the Resources directory and how to reference files in the Resources folder. What is the “Resources” folder? When creating a...
An Easier Way to Set Boolean Advanced Flags in Dymola
There are many advanced flags within Dymola that allow you to control how it works, but it has not always been straightforward to find out what advanced flags are available and where these can be set. From Dymola 2019 FD01, there has been a new way to display and...
Comparing the performance of different radar systems within the virtual environment of rFpro
Many companies are currently developing radar sensors for the autonomous driving application and each system made available will have unique specifications and thus capabilities. To gain a sufficient amount of radar measurements in the real-world, to confirm that a given sensor meets certain requirements, will be both time consuming...
The Advantages of Expandable Connectors
A connector is a Modelica class with the objective of interfacing two or more components/objects together. This said, one of the areas with higher relevance in Dymola is the connectors since they are the means that let the information flow through every component and therefore allow the model objects to...
The importance of vehicle dynamics for ADAS and Autonomous Vehicle testing
There is a lot of effort being put into the development of virtual test environments for ADAS and AV. One aspect that seems to be ignored by many is the need for high fidelity road models and vehicle dynamics models. Whilst in the early stages of the development of...
