Modules
module	mesh_oct_m
	This module defines the meshes, which are used in Octopus.

Data Types
type	mesh_oct_m::mesh_t
	Describes mesh distribution to nodes. More...
type	mesh_oct_m::mesh_plane_t
	define a grid on a plane. More...
type	mesh_oct_m::mesh_line_t
	This data type defines a line, and a regular grid defined on this line (or rather, on a portion of this line). NB: only works for 2D grids. More...

Functions/Subroutines
subroutine	mesh_oct_m::mesh_init (this)
subroutine, public	mesh_oct_m::mesh_double_box (space, mesh, alpha, db)
	finds the dimension of a box doubled in the non-periodic dimensions More...
subroutine, public	mesh_oct_m::mesh_write_info (this, iunit, namespace)
pure subroutine, public	mesh_oct_m::mesh_r (mesh, ip, rr, origin, coords)
	return the distance to the origin for a given grid point More...
subroutine	mesh_oct_m::mesh_r_global (mesh, ipg, rr, origin, coords)
	return the distance to the origin for a given grid point More...
integer function, public	mesh_oct_m::mesh_nearest_point (mesh, pos, dmin, rankmin)
	Returns the index of the point which is nearest to a given vector position pos. More...
subroutine, public	mesh_oct_m::mesh_discretize_values_to_mesh (mesh, values)
	Assign a set of values to their nearest discrete points on the mesh. More...
real(real64) function, public	mesh_oct_m::mesh_gcutoff (mesh)
	mesh_gcutoff returns the "natural" band limitation of the grid mesh, in terms of the maximum G vector. For a cubic regular grid, it is M_PI/spacing. More...
subroutine, public	mesh_oct_m::mesh_write_fingerprint (mesh, dir, filename, mpi_grp, namespace, ierr)
subroutine, public	mesh_oct_m::mesh_read_fingerprint (mesh, dir, filename, mpi_grp, namespace, read_np_part, read_np, bits, type, offset, nn, ierr)
	This function reads the fingerprint of a mesh written in filename. If the meshes are equal (same fingerprint) return values are 0, otherwise it returns the size of the mesh stored. fingerprint cannot be read, it returns ierr /= 0. More...
subroutine, public	mesh_oct_m::mesh_check_dump_compatibility (mesh, dir, filename, namespace, mpi_grp, grid_changed, grid_reordered, map, ierr)
recursive subroutine, public	mesh_oct_m::mesh_end (this)
integer(int64) function, public	mesh_oct_m::mesh_periodic_point (mesh, space, ip)
	This function returns the point inside the grid corresponding to a boundary point when PBCs are used. In case the point does not have a correspondence (i.e. other BCs are used in that direction), the same point is returned. Note that this function returns a global point number when parallelization in domains is used. More...
integer(int64) function, public	mesh_oct_m::mesh_periodic_point_global (mesh, space, ipg_in)
real(real64) pure function, public	mesh_oct_m::mesh_global_memory (mesh)

logical pure function, public	mesh_oct_m::mesh_compact_boundaries (mesh)
subroutine, public	mesh_oct_m::mesh_check_symmetries (mesh, symm, periodic_dim)
integer(int64) function, public	mesh_oct_m::mesh_global_index_from_coords (mesh, ix)
	This function returns the true global index of the point for a given vector of integer coordinates. More...
subroutine, public	mesh_oct_m::mesh_global_index_to_coords (mesh, ipg, ix)
	Given a global point index, this function returns the set of integer coordinates of the point. More...
integer function, public	mesh_oct_m::mesh_local_index_from_coords (mesh, ix)
	This function returns the local index of the point for a given vector of integer coordinates. More...
subroutine, public	mesh_oct_m::mesh_local_index_to_coords (mesh, ip, ix)
	Given a local point index, this function returns the set of integer coordinates of the point. More...
integer(int64) function, public	mesh_oct_m::mesh_local2global (mesh, ip)
	This function returns the global mesh index for a given local index. More...
integer function, public	mesh_oct_m::mesh_global2local (mesh, ipg)
	This function returns the local mesh index for a given global index. More...
subroutine, public	mesh_oct_m::mesh_minmaxloc (mesh, min_or_max, rank_min_or_max, op)
	Given a local min/max this returns the global min/max and the rank where this is located. More...
