class IntervalMesh

Parent class(es)

• Mesh

Interval mesh of the 1D line [a,b]. Given the number of cells (n) in the axial direction, the total number of intervals will be n and the total number of vertices will be (n + 1).

static Mesh create(std::size_t n, std::array<double, 2> x)

Factory

@param n (std::size_t)

The number of cells.

@param x (std::array<double, 2>)

The end points

@code{.cpp}

// Create a mesh of 25 cells in the interval [-1,1] auto mesh = IntervalMesh::create(25, {-1.0, 1.0});

@endcode

static Mesh create(MPI_Comm comm, std::size_t n, std::array<double, 2> x)

Factory

@param comm (MPI_Comm)

MPI communicator

@param n (std::size_t)

The number of cells.

@param x (std::array<double, 2>)

The end points

@code{.cpp}

// Create a mesh of 25 cells in the interval [-1,1] IntervalMesh mesh(MPI_COMM_WORLD, 25, -1.0, 1.0);

@endcode

IntervalMesh(std::size_t n, double a, double b)

Constructor

@param n (std::size_t)

@endcode

IntervalMesh(MPI_Comm comm, std::size_t n, double a, double b)

Constructor

@param comm (MPI_Comm)

MPI communicator

@param n (std::size_t)

The number of cells.

@param a (double)

The minimum point (inclusive).

@param b (double)

The maximum point (inclusive).

@code{.cpp}

// Create a mesh of 25 cells in the interval [-1,1] IntervalMesh mesh(MPI_COMM_WORLD, 25, -1.0, 1.0);
