Time	Narration
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.

03:46	It is completely free.
03:48	It has excellent thermodynamics and solvers.
03:52	The entire source code is available to everyone.
03:56	Manuals of DWSIM explain every calculation.
04:00	Commercial simulators keep these confidential.
04:04	The user can introduce models, compounds and thermodynamics.
04:09	One can also use DWSIM’s thermodynamic library with other programs.
04:15	We have excellent spoken tutorials on DWSIM.
04:19	We will begin with the creation of material streams in DWSIM.
04:24	I have already downloaded all the spoken tutorials.
04:29	I will play them one by one.
04:32	Let me play this.Add video audio clip of Creating a material Stream in DWSIM---
04:40	The next tutorial is an introduction to Flowsheeting.
04:45	This constructs a simple flowsheet with a flash and a mixer.
04:50	Let us listen to it.
04:53	Add video audio clip of Introduction to Flowsheeting in DWSIM.
04:59	The next tutorial explains how to simulate a distillation column through shortcut.
05:07	Let us listen to it.
05:10	Add video audio clip of simulating a shortcut distillation column in DWSIM.---
05:17	The next tutorial explains how to carry out rigorous distillation calculations.
05:23	The starting point for this is shortcut distillation.
05:27	Let us listen to it.
05:30	Add video audio clip of simulating a rigorous distillation column in DWSIM.
05:36	The final tutorial I plan to show explains how to do sensitivity analysis.
05:42	Helps do a sensitivity study of some variables on other variables.
05:49	The adjust operation does the same thing automatically.
05:54	Add video audio clip of Sensitivity Analysis, Adjust.
06:04	Here is a summary of the tutorials we just saw.
06:10	Using DWSIM, one can quickly find solutions to flowsheeting problems.
06:15	Carry out "what if" studies.
06:18	Identify bottlenecks and ways to increase the throughput.
06:23	Students will find DWSIM extremely useful.
06:27	It will help them understand the concepts well.
06:29	Their expertise will help improve profits in industry.
06:34	They will get a lot more core engineering jobs.
06:38	It is also useful to those students who want to start a consulting company.
06:43	You may think that because it is an open source software, no help is available.
06:49	Is this true?
06:51	It is not at all true.
06:53	A lot of help is available to the users of DWSIM.
06:57	I will explain them one by one.
