class IntervalMesh

Parent class(es)

• Mesh

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

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

Constructor

Arguments

nx (std::size_t)

The number of cells.

a (double)

The minimum point (inclusive).

b (double)

The maximum point (inclusive).

Example

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

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

Constructor

Arguments

comm (MPI_Comm)

MPI communicator

nx (std::size_t)

The number of cells.

a (double)

The minimum point (inclusive).

b (double)

The maximum point (inclusive).

Example

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