     3== PALM group ==
     4Our main research tool is the parallelized Large-Eddy Simulation (LES) Model PALM, the original version of which was developed from 1997-1999 at our institute. This model is optimized for use on massively parallel computers, and it is therefore very well suited for simulations with an extremely large number of grid points. The current supercomputer of the North German Supercomputing Center "Norddeutscher Verbund für Hoch- und Höchstleistungsrechnen" (HLRN), an SGI-ICE machine with 12000 cores, allows calculations with up to 40963 grid points.

     6Further information on PALM is available using the PALM quick links below.

     8Our research focusses on the analysis of micro- and mesoscale turbulent boundary layers. Other key parts of our work include numerical improvements of PALM, in particular parallelized numerical schemes, and the development of software systems that are able to effectively visualize the extremely large data amount that is typical of parallelized models.
