Time Narration
00:01 Welcome to the Spoken Tutorial on Overview of OpenModelica.
00:06 In this tutorial, we will learn: About OpenModelica
00:11 Modeling & Simulation
00:14 Subsystems of OpenModelica Environment
00:18 Features of OpenModelica
00:21 Content available in various tutorials under this series
00:26 To record this tutorial, I am using OpenModelica version 1.12.0 and Ubuntu Linux OS 16.04
00:37 What is OpenModelica?

OpenModelica is An open-source modeling and simulation environment

00:45 Object-oriented, multi-domain modeling language for complex systems
00:51 Intended for both industrial and academic purposes
00:56 There are many commercial modeling and simulation tools like: Dymola
01:02 COMSOL Multiphysics

Simulink

01:07 What is Modeling?

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

01:16 What is Simulation?

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

01:27 It allows evaluation of a model to optimize the system performance

And makes predictions about a real system

01:37 OpenModelica has a number of subsystems integrated in its environment.
01:44 Few of the important subsystems are:
01:47 OMNotebook:

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

01:57 OMEdit: This is a graphical connection editor, for component based model design.
02:05 OMOptim:

It extends the capabilities of OpenModelica towards design optimization.

02:13 OMShell:

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

02:21 I have already opened the OMEdit window here.
02:25 You can see a lot of menus and exciting capabilities in OMEdit.
02:31 All of these will be explained in detail later in this series.
02:37 Now I will go the slides.
02:40 Let me point out some advantages of OpenModelica.
02:44 It is completely free of cost and free to use and distribute.
02:49 It has excellent solvers.
02:52 It is an equation oriented environment.
02:56 It has brilliant capability to solve Ordinary Differential Equations.
03:02 Users can create their own models using OpenModelica.
03:07 Now, we will briefly go through the individual tutorials in this series.
03:13 I have opened all these tutorials on separate tabs in my browser window.

Let me go through them one by one.

03:22 We will begin with the first tutorial Introduction to OMEdit.
