Learning Objectives

• About OpenModelica
• Modeling & Simulation
• Subsystems of OpenModelica Environment
• Features of OpenModelica
• Content available in various tutorials under this series.

System Requirements

• OpenModelica version 1.12.0 and
• Ubuntu Linux OS 16.04

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

Commercial modeling and simulation tool

• Dymola
• COMSOL Multiphysics
• Simulink

What is Modeling?

Translating the actual process behaviour into mathematical expressions is called Modeling.

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.

Subsystems of OpenModelica Environment

Few of the important subsystems are:

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.

OpenModelica Optimization Editor (OMOptim)

OpenModelica Shell (OMShell)

It extends the capabilities of OpenModelica towards design optimization.

OMShell:

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

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

Features of OpenModelica

It has excellent solvers.

It is an equation oriented environment.

It has brilliant capability to solve Ordinary Differential Equations.

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

Let’s go through them one by one.

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

This tutorial demonstrates how to simulate existing Modelica library examples.

This tutorial will explain how to-

• Drag and drop different classes
• Connect them to build a system

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

This tutorial demonstrates how to

• Use if-else statement
• when statement
• Handle time & state events.

This tutorial demonstrates how to

• Define a function and
• Type and use an algorithm

This tutorial will explain how to-

• Declare array variables
• Construct arrays,
• Use for and while loops and use OMShell.

This tutorial will explain how to-

• Use array construction functions
• Array conversion functions
• Perform arithmetic operations on vectors and matrices.

This tutorial demonstrates how to

• Create a package
• Import a package

This tutorial demonstrates how to

• Specify an annotation
• Define a record

This tutorial will explain how to-

• Specify icon and diagram views
• Insert shapes in icon and diagram view

This tutorial will explain how to-

• Instantiate a model
• Define connector classes

This tutorial will explain how to-

• Use MISO block
• Instantiate functions

About the Spoken Tutorial Project

http://spoken-tutorial.org/

It summarizes the Spoken Tutorial project.

Spoken Tutorial Workshops

• Conducts workshops using spoken tutorials
• Gives certificates to those who pass an online test
• For more details, please write to contact@spoken-tutorial.org

Forum slide

Choose the minute and second where you have the question.

Explain your question briefly.

Someone from the FOSSEE team will answer them.

Please do not post unrelated and general questions on them.

This will help reduce the clutter.

With less clutter, we can use this discussions as instructional material.

Textbook Companion Project

We give honorarium and certificates for those who do this.
