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
