Detailed Description
Defines an abstract grid volume mesh.
This class defines a mesh of which topology is a regular grid made of num_x * num_y * num_z nodes. Each node with index (i,j,k) in the mesh (except for points along the mesh border) is connected to six points with indices (i+1,j,k), (i,j+1,k), (i-1,j,k), (i,j-1,k), (i,j,k-1), (i,j,k+1).
The values on the mesh nodes are defined by the PbMesh::addValuesSet() method, where argument val is an array of num_x * num_y * num_z floats.

Defines a volume mesh geometry.
The size of the x array depends on the derived class that calls this method. It is either num_x or num_x * num_y * num_z. Idem for y and z array.
