Important Notes : - 

These are the collection of lectures notes . Our subjective is to help students to find all engineering notes with different lectures slides in power point, pdf or html file at one place. Because we always face that we lose much time by searching in  Google or yahoo like search engines to find or downloading a good lecture notes in our subject area. Also it is difficult to find popular authoress or books slides with free of cost.

    If you find any copyrighted slides or notes then please inform us immediately by comments or email as following address .I will take actions to remove it. Please click bellow to download ppt slides/ pdf notes. If you face any problem in downloading or if you find any link not correctly work or if you have any idea to improve this blog/site or if you find any written mistake or you think some subjects notes should be include then give your suggestion as comment by clicking on comment link bellow the post (bottom of page) or email us in this address engineeringppt.blogspot@gmail.com?subject=comments on engineeringppt.blogspot.com. I will must consider your comments only within 1-2 days.

If you have any good class notes/lecture slides in ppt or pdf or html format then please you upload these files to rapidshare.come and send us links or all files by our email address engineeringppt.blogspot@gmail.com?subject=comments on engineeringppt.blogspot.com.

To find your notes quickly please see the contents on the right hand side of this page which is alphabetically arranged and right click on it. After clicking immediately you find all the notes ppt / pdf / html / video of your searching subjects.

It is better to search your subject notes by clicking on search button which is present at middle of right side of this web page. Then enter your subject and press enter key then you can find all of your lectures notes and click on it.

Introduction to Modeling and Simulation

Introduction to Modeling and Simulation

As taught in: Spring 2008

Level:

Undergraduate

Instructors:

Markus Buehler

Raúl Radovitzky

Timo Thonhauser

A graph showing simulation techniques as number of particles, lengths, and times increases from ~100-10^23, angstroms to meters, and picoseconds to seconds, respectively.
Systems at different time and length scales are modeled using different simulation techniques, derived from the appropriate governing equations. (Image courtesy of Elsevier, Inc., Science Direct. Used with permission.)

Course Description

This course explores the basic concepts of computer modeling and simulation in science and engineering. We'll use techniques and software for simulation, data analysis and visualization. Continuum, mesoscale, atomistic and quantum methods are used to study fundamental and applied problems in physics, chemistry, materials science, mechanics, engineering, and biology. Examples drawn from the disciplines above are used to understand or characterize complex structures and materials, and complement experimental observations.

Syllabus

Description

This subject provides an introduction to modeling and simulation. Scientists and engineers have long used models to better understand the system they study, for analysis and quantification, performance prediction and design. This subject will provide you with the relevant theoretical and numerical tools that are necessary to build models of complex physical phenomena and to simulate their behavior using computers. The physical system can be a collection of electrons and nuclei/core shells, atoms, molecules, structural elements, grains, or a continuum medium. The lectures will provide an exposure to areas of application, based on the scientific exploitation of the power of computation.

Instructors

The subject will be taught by three instructors, each covering approximately one third of the subject. Each lecturer will teach a consecutive set of 7 or 8 lectures (part I, Lec #2-9, Raúl Radovitzky, continuum methods; part II, Lec #10-18, Markus Buehler, atomistic and molecular methods; part III, Lec #19-27, Timo Thonhauser, quantum mechanics). The three parts are not independent. Instead, they will base on one another and are integrated.

Lectures

Detailed lecture notes will be distributed for each lecture, usually covering "theoretical" aspects (derivations, concepts etc.) in more detail or in a different manner than done during class. The subject content is defined by the material presented in lectures, recitations and reading assignments, so regular attendance is advisable.
