cell_split_size:400# (Optional) Maximal number of particles per cell (this is the default value).
max_top_level_cells:12# (Optional) Maximal number of top-level cells in any dimension. The number of top-level cells will be the cube of this (this is the default value).
tasks_per_cell:0# (Optional) The average number of tasks per cell. If not large enough the simulation will fail (means guess...).
mpi_message_limit:4194304# (Optional) Maximum MPI task message size to send non-buffered
mpi_message_limit:4096# (Optional) Maximum MPI task message size to send non-buffered, KB.
# Parameters governing the time integration (Set dt_min and dt_max to the same value for a fixed time-step run.)
