Detailed Description

Mesh geometry definion.

Class contains mesh geometry definition. It stores geometry mode (geom_mode), number of mesh nodes in each direction (size), the mesh cell size (h) and the locations of mesh node (0,0,0) and (size[0]-1,size[1]-1,size[2]-1) (known as origo and max). The max point is internally calculated. Other parameters are given when Mesh is constructed.

Mesh is to be used as a base class in all classes, which store or process some kind of mesh data.
