| 00:01 | Welcome to this overview spoken tutorial on DWSIM, an open source chemical process simulator. |
| 00:07 | My name is Kannan Moudgalya. |
| 00:11 | In this tutorial, we will:* learn to install DWSIM |
| 00:15 | Get introduced to DWSIM |
| 00:18 | Get a glimpse of DWSIM spoken tutorials that are already available |
| 00:23 | Learn about all possible help available for DWSIM. |
| 00:28 | Almost any operating system will work, but I am recording this tutorial in Windows 7. |
| 00:34 | What is simulation? |
| 00:36 | Study of a physical system with a mathematical model and a computer solution to this model. |
| 00:43 | Simulation helps predict the behavior of the physical system. |
| 00:47 | It is inexpensive, safe and fast. |
| 00:51 | It eliminates the need to do these studies on the real system. |
| 00:56 | Indian space missions are economical and done in a relatively short time. |
| 01:02 | One important reason is simulation. |
| 01:05 | Reliance Jamnagar was the world’s largest single stream refinery when started. |
| 01:11 | Put up in a short time, once again, thanks to simulation. |
| 01:16 | There are many commercial process simulators. |
| 01:19 | A few general purpose simulators are listed here. |
| 01:23 | What is DWSIM? It is a state of the art process simulator, Open source software, absolutely free, developed by Daniel Thermodynamic support by Gregor, used all over the world. |
| 01:39 | I will now explain how to install DWSIM in Windows 7. |
| 01:45 | Go to the link shown here. |
| 01:50 | I am already at this link. Click the Download button. |
