class UnitSquareMesh

Parent class(es)

• RectangleMesh

Triangular mesh of the 2D unit square [0,1] x [0,1]. 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).

std::string diagonal (“left”, “right”, “right/left”, “left/right”, or “crossed”) indicates the direction of the diagonals.

UnitSquareMesh(std::size_t nx, std::size_t ny, std::string diagonal="right")

Create a uniform finite element Mesh over the unit square [0,1] x [0,1].

Arguments

nx (std::size_t)

Number of cells in horizontal direction.

ny (std::size_t)

Number of cells in vertical direction.

diagonal (std::string)

Optional argument: A std::string indicating the direction of the diagonals.

Example

UnitSquareMesh mesh1(32, 32);
UnitSquareMesh mesh2(32, 32, "crossed");

UnitSquareMesh(MPI_Comm comm, std::size_t nx, std::size_t ny, std::string diagonal="right")

Create a uniform finite element Mesh over the unit square [0,1] x [0,1].

Arguments

comm (MPI_Comm)

MPI communicator

nx (std::size_t)

Number of cells in horizontal direction.

ny (std::size_t)

Number of cells in vertical direction.

diagonal (std::string)

Optional argument: A std::string indicating the direction of the diagonals.

Example

UnitSquareMesh mesh1(MPI_COMM_WORLD, 32, 32);
UnitSquareMesh mesh2(MPI_COMM_WORLD, 32, 32, "crossed");
