As vehicles are getting more complex as integrated mechatronic systems, approaches which are cross-disciplinary using simulation are now vital. Development processes need to be able to capture and understand all the permutations of each design change or choice, which cannot be easily discretised into singular studies, whether physical or...

Dymola Basics: 9. Modelica Language – Calculations
This blog post is a continuation from a previous post on the Modelica Language. This blog post focuses on the syntax used in equations and algorithms and the difference between the two. Calculations Equation Sections Models and blocks primarily use an equation section to define the calculations of the...
Dymola Basics: 9. Modelica Language – Variables
This blog post is a continuation from a previous post on the Modelica Language. This blog post goes into a little more detail regarding variable definition and syntax in equations and algorithms. The Class Restriction of a class can restrict the ability to use certain elements and methods, also described...
Dymola Basics: 9. Modelica Language – Classes
Once you’ve got comfortable with creating models using components in the Diagram layer you will probably need to create your own models. This requires understanding and implementation of the Modelica language. This, like any other coding language, must be written in the correct order, with the correct punctuation. This...
Searching of the Modelica Expandable Connectors’ Signals and their Connected Components in Dymola
Abstract: This blog post is aimed to describe the Find Connection command available in Dymola. This Dymola command is helpful for searching of signals created within large Modelica models especially using Modelica expandable connector. For demonstrating the features of this command, a Hybrid Electric Vehicle example available in a...
Troubleshooting A Failing Dymola Model
There are lots of reasons why a model can fail and sometimes it feels like an endless battle just keeping models running. But what do you do if there is a model that used to run and for some unknown reason it just doesn’t any more? Or a model...
The Dirty Code Layer (and other Dymola Faux Pas)
Have you ever picked up someone else’s Dymola models (or even ones you’ve built in the past) and thought to yourself – WHAT A MESS!? – or WHAT IN THE WORLD WAS I DOING HERE?! Organization is the first step to eliminating this sort of response. When creating models...
Modelica-based Tic and Toc Functions in Dymola
Abstract: This article is aimed to present Modelica-based simple tic and toc functions and their implementation in Dymola. These functions are created to estimate the total elapsed computer processing unit (CPU) time of repeated model experimentations in Dymola. For this purpose, the getTime() function from Modelica Standard Library (MSL)...
