As there are already enough websites out there, this page only provides content and no personal data. Due to various reasons I don't provide all stuff for direct download. If you want to have some of the files described in this website or some further information, please drop me a mail.

Movies

In this section some movies of my atomistic simulations are shown.

Generation of Plasticity under Indentation in (100) Copper

The plastic deformation under loading with a spherical indenter can easily be investigated using atomistic simulations.

Xmas Simulations

Using computer simulations it is possible - believe it or not - to set up useless configurations. Some examples are given below :)

Linux

In this section some snipplets of my software are published. Consider all of this software as not even alpha, as I'm only interested in hacking it for my own purpose. If somebody is interested in taking over any of the projects, feel free to do so :) All the software snipplets I wrote are provided under the GPLv3, of course.

Physics Software

As this is scientific research software it is under heavy development and probably unuseable for others. Drop me a mail if you are interested in this code...
