Axel Arnold (FOM-institute AMOLF, Amsterdam, the Netherlands) Title: ESPResSo Abstract: We present the MD simulation package ESPResSo. ESPResSo stands for Extensible Simulation Package for RESearch on SOft matter systems, and is a flexible and extensible simulation code which allows a broad range of applications in for example polymer science, biophysics, solid state physics or chemistry. It is a parallel code specifically designed for the investigation of bead spring models, and contains many state-of-the-art algorithms. The code is available under terms of the GNU public license. We show some examples of simulations that have been performed using ESPResSo as well as a short introduction into the script interface. [See also: http://www.espresso.mpg.de ]
