Added the EAGLE_6 test case. This is a very small cosmological volume not representative of the workload of large runs.
parent 1f3c79fa
ICs extracted from the EAGLE suite of simulations.
WARNING: These ICs correspond to a very small cosmological volume
and are not representative of actual load-balancing of large runs.
The particle distribution here is the snapshot 27 (z=0.1) of the 6.25Mpc
Ref-model. h- and a- factors from the original Gadget code have been
corrected for. Variables not used in a pure hydro & gravity code have
been removed.
Everything is ready to be run without cosmological integration.
