The FLASH Code at Hamburg Observatory

Members of the observatory in Hamburg extensively use and contribute to the development of the FLASH code, a 3-dimensional (magneto-)hydrodynamic code for astrophysical supercomputing applications. The code is mainly developed and maintained at the FLASH Center of the University of Chicago.


We apply the FLASH code for studying a variety of astrophysical problems:

  • magnetic fields and star formation in disc galaxies,
  • formation and evolution of molecular clouds, including feedback,
  • formation of star clusters,
  • dynamics of extrasolar planets around massive stars and binary systems,
  • and magnetic fields in the early Universe.


We also develop new modules for the FLASH code to extend its applicability or to increase its efficiency and accuracy. Modules developed and tested at Hamburg Observatory so far include:


For our simulation projects and code development we use the GPU cluster GOLEM hosted at the observatory, computational resources provided by the Computing Center of the University of Hamburg (RRZ), and external HPC facilities, such as HLRN-III.
