Dymola 2020 workflow tips & tricks: shortcuts
We’re all familiar with shortcuts to improve workflow. Some are widely known, such as Ctrl + C and Ctrl + V to quickly copy and paste text or images (or components/models in Dymola). Others are not, but that doesn’t make them less handy. Here are 3 simple Dymola shortcuts...
Playing Pool in Dymola
While developing libraries there are many ideas that dawn on me that are normally accompanied by the phrase “How hard could it be to….”. This is the result of one of those thoughts. While developing ground contact models for our VeSyMA – Motorsports, 1D and 2D tests were created...
Synchronisers in Dymola: VeSyMA – Powertrain
INTRODUCTION A synchroniser can be defined as a crucial internal shifting element present in manual, automated manual and dual clutch transmissions. Its objective is to match the circumferential speeds of parts to be connected in short periods of time with the application of minimal force, in the same way...
What’s new in Dymola 2020?
With the release of the latest version of Dymola, 2020, comes a slew of new features. Notably, this version of Dymola arrives with the latest edition of the Modelica Standard Library, version 3.2.3. Here’s a selection of the highlights in Dymola 2020. Plotting connector variables Earlier, my colleague Alessandro...
Magic T-Handles in Space: Simulating 3D Rotational Dynamics in Modelica
Everyday objects rarely move in ways that surprise us. One does not need an understanding of physics to catch a ball— human intuition is enough to predict its path. Knowledge of gravity and momentum is useful for quantifying and explaining the arc the ball follows, but it is not...
Shopping Trolley or Shopping Cart?
Since moving from the UK to the USA in 2018, I’ve noticed various little differences beyond the obvious between the two countries. Some are positive differences, like actual sunshine, decently sized parking spaces, drive-thru post boxes and cheap petrol. Other differences however are less than ideal, such as polar...
Variable valve timing on the effect of brake specific fuel consumption (BSFC) improvement: a study at part load using VeSyMA – Engines
The effects of continuously variable valve timing (VVT) are relatively well known. This blog post carries out an investigation at part load condition (3000 RPM, 3 Bar BMEP) for a three-cylinder 1 Litre SI engine with VVT to analyse the benefit of VVT on fuel consumption. All experiments are...
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....
