Detailed Description

Defines an abstract grid surface mesh.

This class defines a mesh of which topology is a regular grid made of num_x

num_y nodes. Each node 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).

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.
