## hexahedron

(hĕk'səhē`drən): see cubecube,
in geometry, regular solid bounded by six equal squares. All adjacent faces of a cube are perpendicular to each other; any one face of a cube may be its base. The dimensions of a cube are the lengths of the three edges which meet at any vertex.
; polyhedronpolyhedron
, closed solid bounded by plane faces; each face of a polyhedron is a polygon. A cube is a polyhedron bounded by six polygons (in this case squares) meeting at right angles.

A hexahedral grid is used for both domains; points are equally spaced in streamwise and spanwise/azimuthal directions for both channel and pipe, while a nonuniform discretization was used for the wall normal direction in order to obtain a finer grid next to the wall.
The model was discretized using hexahedral elements for the joists and tetrahedral elements for the slab and screws.
