SPH::Mesh Class Reference

Abstract base class for cell-based mesh by introducing number of cells, buffer width and mesh-based data in its derived classes. Note that we identify the difference between grid spacing and data spacing. The latter is different from grid spacing when MeshWithDataPackage is considered. More...

Detailed Description

Abstract base class for cell-based mesh by introducing number of cells, buffer width and mesh-based data in its derived classes. Note that we identify the difference between grid spacing and data spacing. The latter is different from grid spacing when MeshWithDataPackage is considered.
