Built-in meshes

This demo illustrates:

• How to define some of the different built-in meshes in DOLFIN

Implementation

Running this demo requires the files: main.cpp and CMakeLists.txt.

Under construction

#include <dolfin.h>

using namespace dolfin;

int main()
{
  if (dolfin::MPI::size(MPI_COMM_WORLD) == 1)
  {
    UnitIntervalMesh interval(10);
    info("Plotting a UnitIntervalMesh");
    plot(interval, "Unit interval");
  }

  UnitSquareMesh square_default(10, 10);
  info("Plotting a UnitSquareMesh");
  plot(square_default, "Unit square");

  UnitSquareMesh square_left(10, 10, "left");
  info("Plotting a UnitSquareMesh");
  plot(square_left, "Unit square (left)");

  UnitSquareMesh square_crossed(10, 10, "crossed");
  info("Plotting a UnitSquareMesh");
  plot(square_crossed, "Unit square (crossed)");

  UnitSquareMesh square_right_left(10, 10, "right/left");
  info("Plotting a UnitSquareMesh");
  plot(square_right_left, "Unit square (right/left)");

  RectangleMesh rectangle_default(Point(0.0, 0.0), Point(10.0, 4.0), 10, 10);
  info("Plotting a RectangleMesh");
  plot(rectangle_default, "Rectangle");

  RectangleMesh rectangle_right_left(Point(-3.0, 2.0), Point(7.0, 6.0), 10, 10, "right/left");
  info("Plotting a RectangleMesh");
  plot(rectangle_right_left, "Rectangle (right/left)");

  UnitCubeMesh cube(10, 10, 10);
  info("Plotting a UnitCubeMesh");
  plot(cube, "Unit cube");

  BoxMesh box(Point(0.0, 0.0, 0.0), Point(10.0, 4.0, 2.0), 10, 10, 10);
  info("Plotting a BoxMesh");
  plot(box, "Box");
