I spend a lot of time looking at Dymola models created by others, and a big factor in a model’s user friendliness is the quality of the documentation included. So in this blog post, I’m going to take a look at the documentation options available in Dymola. Documenting Code...
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 creating a vehicle, one of the first things you need to establish is the origins and coordinate systems. This is the seed from which the rest of the vehicle grows from and it’s always best to know which direction is up. Further complications can arise when you’ve got...
We wrote about the installation of Dymola on Linux earlier on in 2021. This blog post looks at giving a quick guide to installation of Dymola on Windows. The Dymola installer is the same regardless of whether you have a Dymola licence or not. It is the licence that...
Dymola is a tool built around advanced symbolic manipulation. Many solver algorithms and numerical methods are / can be utilized to solve the models created within Dymola. Many of the algorithms and numerical methods have substantial impact on the accuracy and speed of the resulting simulations. Jacobian matrices play...
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 post looks at installing Dymola on Ubuntu for users that are not experienced with Linux. The installation process is described in the documentation however this can be daunting for Linux novices so a step by step process is provided. Requirements There are some things that this post assumes...
Scenario Editor is a tool for the creation, modification and storage of scenarios for use in rFpro and Dymola. Scenario Editor allows users to view an OpenDRIVE map (.xodr file) and then plot a route around the road network while adding events such as stops and lane changes. For...
Before getting involved in advanced ways of modelling we need to make sure the basics are in place. The better we set out the class in the first place, the easier our lives will be later on in the modelling. I have written blog posts in this area in...
I was recently asked why Dymola/Modelica simulations are so prevalent in Motorsport, which made me think back to 2008 when I first started using this simulation package. You may be expecting an answer about symbolic manipulation, object oriented behavior, short learning curves or a number of other things. After...
