Applied physics
- Self-gravity
- Self-Gravity is applied.
- Star formation
- Star formation is treated using Lagrangian sink particles that accrete the surrounding gas and interact gravitationally with it.
- Hydrodynamics
- Hydrodynamical equations are solved
- Magnetohydrodynamics
- Ideal magneto-hydrodynamics is resolved.
- Supernovae feedback
- No supernovae feedback
