hrweno_grids Module

This module implements a convenience 1D grid class. The module is mostly indented to help write the examples. The WENO schemes themselves are completely independent from this module, so that they can be used anywhere.

Uses

- stdlib_optval
- hrweno_kinds

Graph Key

Nodes of different colours represent the following:

Solid arrows point from a submodule to the (sub)module which it is descended from. Dashed arrows point from a module or program unit to modules which it uses.
Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.
