RectangleMesh¶

class dolfin.cpp.mesh.RectangleMesh(*args)¶

Bases: dolfin.cpp.mesh.Mesh

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).

// Mesh with 8 cells in each direction on the
// set [-1,2] x [-1,2]
Point p0(-1, -1);
Point p1(2, 2);
RectangleMesh mesh(MPI_COMM_WORLD, p0, p1, 8, 8);

Parameters:

comm (MPI_Comm) – (MPI_Comm) MPI communicator
Point & p0 (const) – (Point ) First point.
Point & p1 (const) – (Point ) Second point.
nx (std::size_t) – (double) Number of cells in \(x\) -direction.
ny (std::size_t) – (double) Number of cells in \(y\) -direction.
diagonal (std::string) – (string) Direction of diagonals: “left”, “right”, “left/right”, “crossed”
