This must be directly implemented into the hydro schemes, therefore only a subset of schemes (Gadget-2 and Pressure-Energy) are currently implemented.
This must be directly implemented into the hydro schemes, therefore only a subset of schemes (Gadget-2, SPHENIX and Pressure-Energy) have the floor available.
In order to implement it, you need equation 12 in `Hopkins 2013 <https://arxiv.org/abs/1206.5006>`_:
max_physical_DM_softening:0.5# Maximal Plummer-equivalent softening length in physical coordinates for DM particles (in internal units).
max_physical_baryon_softening:0.5# Maximal Plummer-equivalent softening length in physical coordinates for baryon particles (in internal units).
softening_ratio_background:0.04# Fraction of the mean inter-particle separation to use as Plummer-equivalent softening for the background DM particles.
