Detailed Description

Defines a cartesian grid surface mesh.

Class to define a mesh represented by a grid with cartesian coordinates. This mesh is defined by a matrix num_x * num_y points forming (num_x - 1) * (num_y - 1) quadrangles. Each point with index (i, j) in the mesh (except for points along the mesh border) is connected to four points with indices (i+1,j), (i,j+1), (i-1,j), (i,j-1). x, y and z are array of num_x * num_y floats.

The values on the mesh nodes are defined by the PbMesh::addValuesSet() method, where val argument is an array of num_x * num_y floats.
