Single-softening gravity scheme crash
Some gravity schemes crash planetary (and other non-DM simulations?). e.g. --with-gravity=with-potential
and --with-gravity=basic
for the Planetary/EarthImpact/
example.
It runs fine with --with-gravity=with-multi-softening
, so assumed caused by the code wanting a DM softening that doesn't exist with only hydro particles.
