Detailed Description

Gravitational kernel approximated by LUT for close particles.

At larger distances, we recover the standard Newtonian inverse square law. Implemented according to P. Cossins, PhD thesis, 2010 [6].

It can only be constructed from a precise gravitational kernel or using the default constructor, which corresponds to a point mass. Gravitational kernels can be created by specializing GravityKernel class template or by deriving from GravityKernelTag. This is required to avoid accidentally creating GravityLutKernel from SPH kernel.
