class BoxMesh

Parent class(es)

Tetrahedral mesh of the 3D rectangular prism spanned by two points p0 and p1. Given the number of cells (nx, ny, nz) in each direction, the total number of tetrahedra will be 6*nx*ny*nz and the total number of vertices will be (nx + 1)*(ny + 1)*(nz + 1).

BoxMesh(const Point &p0, const Point &p1, std::size_t nx, std::size_t ny, std::size_t nz)

Create a uniform finite element Mesh over the rectangular prism spanned by the two _Point_s p0 and p1. The order of the two points is not important in terms of minimum and maximum coordinates.

@param p0 (Point)
First point.
@param p1 (Point)
Second point.
@param nx (double)
Number of cells in x-direction.
@param ny (double)
Number of cells in y-direction.
@param nz (double)
Number of cells in z-direction.
@code{.cpp}
// Mesh with 8 cells in each direction on the // set [-1,2] x [-1,2] x [-1,2]. Point p0(-1, -1, -1); Point p1(2, 2, 2); BoxMesh mesh(p0, p1, 8, 8, 8);
