Planetary (Density-Energy, Multi-Material) SPH¶
This scheme is the same as the Minimal SPH scheme but also allows multiple materials, meaning that different SPH particles can be assigned different Equations of State (EoS).
To use the planetary scheme and the corresponding planetary EoS, use
./configure --with-hydro=planetary --with-equation-of-state=planetary
Every SPH particle then requires and carries the additional
from the initial conditions file. This flag indicates the particle’s material
and which EoS it should use.
