Visual Cue Narration
Slide Number 1 Welcome to the Spoken Tutorial on Overview of OpenModelica.
Slide Number 2

Learning Objectives

In this tutorial, we will learn about:
  • About OpenModelica
  • Modeling & Simulation
  • Subsystems of OpenModelica Environment
  • Features of OpenModelica
  • Content available in various tutorials under this series
Slide Number 3

System Requirements

To record this tutorial, I am using
  • OpenModelica version 1.12.0 and
  • Ubuntu Linux OS 16.04
Slide Number 4

What is OpenModelica

What is OpenModelica?

OpenModelica is

  • An open-source modeling and simulation environment
  • Object-oriented, multi-domain modeling language for complex systems
  • Intended for both industrial and academic purposes
Slide Number 6


Commercial modeling and simulation tool

There are many commercial modeling and simulation tools like:
  • Dymola
  • COMSOL Multiphysics
  • Simulink
Slide Number 4

What is Modeling?

What is Modeling?

Translating the actual process behaviour into mathematical expressions is called Modeling

Slide Number 5

What is Simulation?

What is Simulation?

Simulation uses a model to study the behaviour and performance of an actual or theoretical system.

  • It allows evaluation of a model to optimize the system performance
  • And makes predictions about a real system.
Slide Number 7


Subsystems of OpenModelica Environment


OpenModelica has a number of subsystems integrated in its environment.


Few of the important subsystems are:

Slide Number 8

OMNotebook DrModelica model editor


OpenModelica Connection Editor (OMEdit)

OMNotebook:

It provides a lightweight notebook editor, compared to the more advanced Mathematica extension.


OMEdit:

This is a graphical connection editor, for component based model design.

Slide Number 9


OpenModelica Optimization Editor (OMOptim)


OpenModelica Shell (OMShell)

OMOptim:

It extends the capabilities of OpenModelica towards design optimization.


OMShell:

It is an interactive command line session handler for Modelica scripting.


Cursor on the interface. I have already opened the OMEdit window here.
Point to the menus. You can see a lot of menus and exciting capabilities in OMEdit.

All of these will be explained in detail later in this series.

Now I will go the slides.
Let me point out some advantages of OpenModelica.
Slide Number 8


Features of OpenModelica

It is completely free of cost and free to use and distribute.

It has excellent solvers.

It is an equation oriented environment.

It has brilliant capability to solve Ordinary Differential Equations.

Users can create their own models using OpenModelica.
ST Slide Now, we will briefly go through the individual tutorials in this series.

I have opened all these tutorials on separate tabs in my browser window.

Let’s go through them one by one.

Introduction to OMEdit slide We will begin with the first tutorial Introduction to OMEdit.

Here we will learn about:

  • Different tools and icons in the OMEdit window
  • How to open a class from the Libraries Browser
  • Use of Simulate & Re-simulate button
Play ST for 10 secs Let me play this tutorial
Examples through OMEdit slide The next tutorial is Examples through OMEdit.

This tutorial demonstrates how to simulate existing Modelica library examples.

Play ST for 10 secs Let us listen to it.
OpenModelica Connectors slide The next tutorial is OpenModelica Connectors.

This tutorial will explain how to-

  • Drag and drop different classes
  • Connect them to build a system
Play ST for 10 secs Here is a glimpse of this tutorial.
Developing an equation based model slide The next tutorial is Developing an equation based model

This tutorial demonstrate on how to create a textual model in OMEdit and simulate it.

Play ST for 10 secs Let me play this tutorial.
Control flow and Event handling slide The next tutorial is Control flow and Event handling.

This tutorial demonstrates how to-

  • Use if-else statement
  • when statement
  • Handle time & state events.
Play ST for 10 secs Let us listen to it.
Functions and Types slide Next comes Functions and Types.

This tutorial demonstrates how to-

  • Define a function and
  • Type and use an algorithm

  • Define a record
Play ST for 10 secs Let me play this for you.
Icon and Diagram Views slide After this comes Icon and Diagram Views.

This tutorial will explain how to-

  • Specify icon and diagram views
  • Insert shapes in icon and diagram view
Play ST for 10 secs Let us listen to it.
Component oriented modeling slide The next tutorial is Component oriented modeling.

This tutorial will explain how to-

  • Instantiate a model
  • Define connector classes
