Detailed Description

Utility class that provides methods for calculating distributions of points on different cells.

Simplicial lattices in PointTools are sets of points with certain ordering properties. They are used for defining degrees of freedom for higher order finite elements.

Each lattice has an "order". In general, this is the same as the cardinality of the polynomial space of degree "order". In terms of binomial coefficients, this is binomial(order+d,order) for the simplex in d dimensions. On the line, the size is order+1. On the triangle and tetrahedron, there are (order+1)(order+2)/2 and (order+1)(order+2)(order+3)/6, respectively.

The points are ordered lexicographically from low to high in increasing spatial dimension. For example, the line lattice of order 3 looks like:

  x--x--x--x

where "x" denotes a point location. These are ordered from left to right, so that the points are labeled:

  0--1--2--3

The triangular lattice of order 3 is

  x
  |\
  | \
  x  x
  |   \
  |    \
  x  x  x
  |      \
  |       \
  x--x--x--x

The ordering starts in the bottom left and increases first from left to right. The ordering is

  9
  |\
  | \
  8  7
  |   \
  |    \
  4  5  6
  |      \
  |       \
  0--1--2--3

Tetrahedral lattices are similar but difficult to draw with ASCII art.

Each lattice also has an "offset", which indicates a number of layers of points on the bounary taken away. All of the lattices above have a 0 offest. In Intrepid, typically only offset = 0 or 1 will be used. The offset=1 case is used to generate sets of points properly inside a given simplex. These are used, for example, to construct points internal to an edge or face for H(curl) and H(div) finite elements.

For example, for a line lattice with order = 3 and offset = 1, the points will look like

  ---x--x---

and a triangle with order=3 and offset=1 will contain a single point

  .
  |\
  | \
  |  \
  |   \
  |    \
  |  x  \
  |      \
  |       \
  |--------\

When points on lattices with nonzero offset are numbered, the are numbered contiguously from 0, so that the line and triangle above are respectively

  ---0--1---

  .
  |\
  | \
  |  \
  |   \
  |    \
  |  0  \
  |      \
  |       \
  |--------\

Additionally, two types of point distributions are currently support. The points may be on an equispaced lattice, which is easy to compute but can lead to numerical ill-conditioning in finite element bases and stiffness matrices. Alternatively, the warp-blend points of Warburton are provided on each lattice (which are just the Gauss-Lobatto points on the line).
