class RectangleMesh

Parent class(es)

Triangular mesh of the 2D rectangle spanned by two points p0 and p1. Given the number of cells (nx, ny) in each direction, the total number of triangles will be 2*nx*ny and the total number of vertices will be (nx + 1)*(ny + 1).

static Mesh create(const std::array<Point, 2> &p, std::array<std::size_t, 2> n, CellType::Type cell_type, std::string diagonal = "right")
@param p (std::array<Point, 2>)
Vertex points.
@param n (std::array<std::size_t, 2>)
Number of cells in each direction
@param cell_type (dolfin::CellType::Type)
Cell type
@param diagonal (string)
Direction of diagonals: “left”, “right”, “left/right”, “crossed”
