Modelica External Object Example: Detecting the Initial Rising Edge
This blog post describes the use of an external object class as described by the Modelica modelling language. In Modelica, a predefined partial class called an ExternalObject may be used for accessing external memory and performing various tasks using external functions written in C (specifically C89) and FORTRAN 77....
Constraining common parameters in a replaceable model
Making flexible models: utilising the replaceable model declaration One of the easiest ways of handling the propagation of a plethora of parameters from model variants designed to be replaceable (sharing a base class) is the replaceable model declaration. As my colleague demonstrates in a previous blog post, such a...
Using VeSyMA to deploy Dymola and rFPro together during vehicle development
Modern vehicles; modern challenges Vehicles are getting ever more complex, with subsystems becoming further interdependent with the wider system dynamics than ever before. Beyond this, modern vehicles now interact with their surroundings, reacting and responding to changes in the immediate environment. This is never truer than in autonomous vehicles....
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...
Modifications introduced in Modelica 3.4
The Modelica Association released the Modelica Language Specification version 3.4 on 15 May 2017. This blog entry summarises the major changes to the language specification with the aim of helping users to be aware of the changes. These changes have been supported in Dymola since Dymola 2018. Main Changes The...
New Features in Dymola 2019
Dymola 2019 is now out and there are many new features that have been added to this new release. More information on these can be found in the official Dymola 2019 Release Notes. DAE mode for more efficient simulation of large models Improved initial guesses for equations in 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...
