The new release of Dymola 2013 brings a variety of new features and improvements to assist the user. Some of the highlights are: Submodel aggregation, providing a convenient way to create submodels from selected sets of components in a few clicks of the mouse. This feature will be elaborated further in a future Tech Blog [...]
Interfacing Dymola and Simulink is quite straight forward. In this example I will look at exporting a simple driven pendulum model from Dymola to Simulink as an s-function. First, create a copy of the example model Modelica.Mechanics.MultiBody.Examples.Elementary.Pendulum model and call it DrivenPendulum. To setup the model for use in Simulink we have to define the [...]
Resizing the Diagram layer By increasing the size of the diagram layer we gain more space to layout graphical model diagrams. To change the size of the diagram follow these steps: Select the class whose diagram layer you wish to resize by double clicking on it in the package browser In Modelling mode, select Attributes [...]
Getting started: running and plotting results
To run a model: Make sure you have selected the model you wish to run in the package browser, do this by double clicking on the model. The name of the selected model will appear in the title bar at the top of the Dymola window. The next step is to select the simulation window [...]
The Modelica language specification defines two ways that a library can be saved. The complete library can be saved as a single Modelica file or it can be mapped to a directory heirarchy. In Dymola this choice is made when creating a new package by the checkbox at the bottom of the dialog, see below. [...]
Getting more from simulation – Part 4: Reusing models for different types of analysis
To download a pdf of this article follow the link Reusing models for different types of analysis In this 4th article in the series “Getting more from simulation” we will explore how component orientated physical modelling supports the extensive reuse of models to perform different analyses. In earlier articles in this series we discussed how [...]
Getting more from simulation – Part 3 Component orientated modelling versus block diagram modelling
Download a copy of the article as a pdf: Component oriented modelling versus block diagrams Written by Mike Dempsey, Claytex In this 3rd article in the series “Getting more from simulation” we will compare the component orientated, physical modelling approach used in Dymola with the traditional block diagram modelling approach used in tools like Simulink.Dymola [...]
Getting more from simulation – Part 2: Component orientated modelling and symbolic manipulation
Download a copy of the article as a PDF: Component Orientated Modelling Dymola In this 2nd article in the series “Getting more from simulation” we explore how the component orientated, physical modelling approach used in Dymola simplifies model creation and accelerates the model development process. What a component orientated modelling approach means in practice is [...]
Getting more from simulation – Part 1
Read this article as a pdf Getting more from simulation – Part 1 It’s time simulation engineers started using the right tool for the job. One of the problems of using traditional simulation tools has been knowing how to interpret what happens in reality and translate that into the abstract representations needed for use in [...]
