| 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. |
