A hybrid 2D+1D AMR extension.
To include this component of the p4est library, configure p4est with the –enable-p6est option given. This module provides a specific kind of anisotropic adaptive mesh refinement for 3D meshes: it organizes the hexahedral cells into columns. Each column has the footprint of a 2D p4est quadrant. The cells within a column can be individually refined vertically, and a whole column of cells can be refined horizontally. When the forest is partitioned, each column is assigned to a single MPI process, i.e., a column cannot be split between processes. Most of the main 2D / 3D interface is available for p6est: refinement and coarsening, balance, ghost layers, and i/o. Finite element nodes can also be created using p6est_lnodes_new(): this creates nodes in the same data structure as p8est_lnodes_new().
