SMDPL (smdpl)
Description
The Small MultiDark Planck simulation belongs to the series of MultiDark simulations with Planck cosmology. Its simulation box has a side length of only 400 Mpc/h, less than half of the MDPL-size. With 38403 particles inside this small box it achieves a mass resolution of 108 Msun/h per dark matter particle. Some more details for this simulation are described in Klypin et al. 2014.
