-To obtain a body-fitted and isotropic particle distribution, an initial configuration (see [Sampling of Geometries](@ref sampling_of_geometries)) is first generated. This configuration is then packed using a [`ParticlePackingSystem`](@ref) following the steps introduced in [neher2025robustefficientpreprocessingtechniques](@cite).
