class UnitSquareMesh

Parent class(es)

Triangular/quadrilateral 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.

static Mesh create(std::array<std::size_t, 2> n, CellType::Type cell_type, std::string diagonal = "right")

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

@param n (std:::array<std::size_t, 2>)
Number of cells in each direction.
@param cell_type
Triangle or quadrilateral
@param diagonal (std::string)
Optional argument: A std::string indicating the direction of the diagonals.

@code{.cpp}

auto mesh1 = UnitSquareMesh::create(32, 32); auto mesh2 = UnitSquareMesh::create(32, 32, “crossed”);

@endcode

static Mesh create(MPI_Comm comm, std::array<std::size_t, 2> n, CellType::Type cell_type, std::string diagonal = "right")

@param comm (MPI_Comm)
MPI communicator
@param n (std:::array<std::size_t, 2>)

@endcode

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