Classes
struct	GravityKernelTag
class	GravityLutKernel
	Gravitational kernel approximated by LUT for close particles. More...
class	GravityKernel< CubicSpline< 3 > >
class	GravityKernel< ThomasCouchmanKernel< 3 > >
	ThomasCouchmanKernel differs from CubicSpline only in the gradient, so the GravityKernel is the same. More...
class	SolidSphereKernel
	Gravity kernel of a solid sphere. More...

struct	IsGravityKernel< T, std::enable_if_t< std::is_base_of< GravityKernelTag, std::decay_t< T > >::value > >

Functions
