Restricted domestic water flow impact on energy consumption.
I thought we’d have a look at some interesting non-automotive applications for my next few blog posts. I’ve been meaning to write some for a while. Speaking to one of my colleagues in South Africa I learnt about his area’s reduced domestic water flow in a bid to save...
Version Control and Dymola
In this blog post I will take you through integrating Dymola with your version control system to support your file management. We won’t cover the merits of using a version control system to manage your models, and the safety net this provides in this blog post but if you...
Torque Converters – The Clutches of Automatic Transmissions
We all know almost by instinct that manual transmissions have a clutch to operate correctly, a device that allows to engage or disengage gears according to the vehicle speed. The engine is a component that when the vehicle is in use is spinning most of the time, however, we may not want...
Dymola and Modelica Explained
Over the years I have come to realise that there are misunderstandings about what Dymola and the modelling language Modelica are and how they relate to one another. This blog post seeks to address the confusion. Dymola (DYnamic MOdelling LAboratory) is a user interface and Modelica language compiler owned...
More Dymola Tips and Tricks
Here are a couple more Dymola tips and tricks that you may want to incorporate into your daily Dymola work. Mark a model as the ‘Simulation Model’ How often has this happened to you? You’re modifying a sub-component of your simulation model and once you complete the change, quickly...
Modelling a flushing toilet in Dymola using Modelica Fluids
A few weeks ago, I was tasked with learning more about fluids modelling within Dymola. Complete with fluids component models, the Modelica Standard Library can be used to model 0-dimensional (0D) and 1-dimensional (1D) fluid systems. As with most things, learning by doing is a good idea. I therefore...
Getting the best out of your simulation software, your demo licenses, and yourself
I have now been using Dymola and Modelica since 2007. Since then, I have learned a lot, been able to help users quite often and developed a few application libraries within Dymola. Some of these libraries have been included in the Dassault Systemes Dymola library portfolio for a number...
Using EGR with a downsized engine for knock mitigation at full load
Down-sizing is very popular in engine design as it reduces fuel consumption while keeping the same power output as the bigger engine by using a turbocharger. A downsized engine uses a smaller cylinder and a higher boosting pressure to yield a higher cylinder pressure over a smaller displacement volume...
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...
