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...
Dassault Systèmes recently released Dymola 2021x, which provides a number of improvements to the modelling and simulation tool. In this blog post, I’m going to highlight some of the changes in Dymola 2021x that you can benefit from. New Modelica Standard Library The Modelica Standard Library supplied has been...
Dassault Systemes have announced the availability of a new version of Dymola. The key highlights of the Dymola 2021x release are: Editing and user interface Select which signals to hide and expose when importing FMU Routing connections around components On popular request: dark mode Simulation Equation dependency graph for simulation analysis Static...
A new training course has been developed to allow students to use the Python Interface with Dymola. The interface, shipped with Dymola, is freely available to use. The half day course focuses on the basics of how to use the interface effectively in any application. Setting up the interface,...
In this blog post I’m going to tell you about the approach we use here at Claytex for our Modelica library development, including some of the tools we use to make our lives easier and our libraries more robust. Some of the factors that influence our development approach are:...
Dymola provides a number of methods for modifying parameters for multiple simulations, such as using the Sweep Parameters tool, using the simulateExtendedModel() function and using translateModel() and simulate() in a batch file. However, the methods as described above cannot be used to modify evaluated parameters. This blog looks at...
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...
There are many ways to control a vehicle in Dymola. This includes constraining it in a rig, using a closed loop driver model or defining open loop controls. But if you want to use it in a Driver-In-The-Loop scenario then the VeSyMA-DiL library will allow you to do that....
This post looks at how the inverse of a function can be provided by using the inverse () annotation. Also, an example is provided where the inverse function is used. Why supply an inverse to a function? During translation, symbolic manipulation will reorder the equations into a form that...
There are many ways to simulate a vehicle following a driving line, but the most realistic results are gained using a driver model. However, a driver model conventionally uses a line to follow, either created from scratch or using reference data. The difficulty is creating a realistic driving line...
