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 5


Commercial modeling and simulation tool

There are many commercial modeling and simulation tools like:
  • Dymola
  • COMSOL Multiphysics
  • Simulink
Slide Number 6

What is Modeling?

What is Modeling?

Translating the actual process behaviour into mathematical expressions is called Modeling

Slide Number 7

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 8


Subsystems of OpenModelica Environment


OpenModelica has a number of subsystems integrated in its environment.


Few of the important subsystems are:

Slide Number 9

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 10


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 11


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.
