**DFG and KONWIHR-WORKSHOP: LBM2001**

Lattice Boltzmann Methods - Theory and Applications in Fluid Mechanics

Erlangen, March, 26th - 28th, 2001

This workshop was organized by LSTM-Erlangen with financial support from DFG and KONWIHR. Internationally recognized scientists gave lectures. Even though the workshop was some years ago, most of the lecture notes are sill of relevance. Some additional lecture notes on lattice Boltzmann topics from other more recent events have also been added below in the download section to make this page even more attractive.

### Program of the LBM2001 workshop

More or less for reference: the original announcement of the workshop as PDF file

### Download of the lecture notes

Most lecture notes of the LBM2001 workshop as well as some
additional material are available for download in PDF format.
These **downloads are provided completely free of charge but
you have to register** (i.e. fill out a short online form)
before you can access the files because we want to track how much
interest in these materials there is. We believe that this
local online form is a much better means than using
*google-analytics* or other (invisible) tracking methods.

#### The procedure is the following:

- Fill out this online-form and you will immediately receive a password by e-mail. Please carefully check your spam folder if you do not see our automatic reply!
- With that password, you can enter the restricted pages (see the links below.
- You
**lost your password**? Just register again and a new password will be sent to you (superseding the previous one if you use the same email address). - Contact webmaster@konwihr.uni-erlangen.de if you have any problems.

## Further information on lattice Boltzmann methods

The number of publications and groups working on lattice Boltzmann methods is growing exponentially. Therefore, the following list is by no means comprehensive. Please feel free to point us to other items we should include!

### Conferences, workshops and tutorials

- The International Conference for Mesoscopic Methods in Engineering and Science (ICMMES) takes place anually since 2004. Usually, there is a tutorial track on the first day of the conference.
- The
*Discrete Simulation of Fluid Dynamics (DSFD)*conference which also takes place anually since 1986 unfortunaltely does not have a central web page. For DSFD2011 have a look at http://dsfd.org/ - LBMethod.org which contains a lot of information put together by the authors of OpenLB

### Some free or commercial lattice Boltzmann codes

- anb - a very basic teaching code (2-D, BGK collision, arbitrary geometries)
- OpenLB - an open source lattice Boltzmann framework
- EXA Corp. - the comany which develops and sells the commercial lattice boltzmann based "PowerFLOW" flow solver

### The lattice Boltzmann mailing list "*lb-methods*"

The basic idea of the "*lb-methods*" mailing
list is an increased information exchange and discussion between
different groups and individuals working with or interested in
lattice Boltzmann methods. For more information visit the
dedicated
webpage on the "*lb-methods*" mailing list which
not only contains information on how to subscribe but also an archive
of the previous postings.

An other platform for exchange on lattice Boltzmann methods can be found in the Forums on LBMethod.org.
