We 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:
- time dependent radiative transfer (Buntemeyer et al., 2016)
- a GPU accelerated gravity solver (Lukat & Banerjee, 2016)
- mutual drag coupling between particles and grid as well as a Leapfrog integrator for particles in cylindrical geometries (Schäfer et al. 2020)
If you have questions or if you are interested in using code modules, contact the FLASH group(flash"AT"hs.uni-hamburg.de) at the observatory.
