Grid - Introduction

Object: Grid

• Grid object mainly consists of two arrays of shared_ptrs. One is for Vertex for position vectors and the other for Cell for connectivity information. Grid does not impose a particular cell structure; it can consist of different cells.

Constructor

• grid() : forms blank grid. It can be used for variable decleration. The constructor however sets default minimum and maximum levels for h-refinement; and cfl number.

• grid( { coord } ) : ( coord -> x, y, z ) forms a grid with a single vertex.

• grid( { {coord0}, {coord1}, ...} ) : forms a grid with many vertices. Connectivity information is not yet defined.

• grid( { {coord0}, {coord1}, ...}, { {cell0}, {cell2}, ... } } ) : forms a grid with many vertices and cells. cell0, cell1 are integers pointing out the order of vertex in the first list, starting from 0.
