CPointCloudAdaptor	Allows custom point cloud data structure to interface with nanoflann. See https://github.com/jlblancoc/nanoflann for more details
CTreeSearchCheckIDExcludeResult	To collect results of nanoflann tree search. In this class, we check the tag of a potential point and add the point to search list if the tag does not match the tag of a point for which neighbors are computed. This is useful when computing neighbor list for contact. In this case, we do not want points from the same particle to be in the contact neighbor lsit. Default result output of nanoflann search uses std::vector<std::pair<size_t, double>>. We prefer to get the index and distance in a separate list
CTreeSearchCheckIDIncludeResult	To collect results of nanoflann tree search. In this class, we check the tag of a potential point and add the point to search list if the tag matches the tag of a point for which neighbors are computed. This is useful when computing neighbor list for peridynamics. In this case, we want points from the same particle to be in the peridynamics neighbor lsit. Default result output of nanoflann search uses std::vector<std::pair<size_t, double>>. We prefer to get the index and distance in a separate list
CTreeSearchResult	To collect results of nanoflann tree search. Default result output of nanoflann search uses std::vector<std::pair<size_t, double>>. We prefer to get the index and distance in a separate list
▼Nparticle	Collection of methods and data related to particle object
CBaseParticle	A class to store particle geometry, nodal discretization, and methods
CParticleTransform	A struct that stores transformation parameters and provides method to transform the particle. Basically, given a reference particle, this provides method to translate, rotate, and scale the reference particle
CRefParticle	A class to store reference particle related data. Consider a case of multiple hexagon-shaped particle related to each other by affine transformation. In such a case, it is possible to consider a reference hexagon particle and store the mesh and other details of only the reference particle. To get the data relevant to specific hexagon particle, one can apply the appropriate transformation on data for the reference hexagon particle
