NAME

prism - Prism reference element

DESCRIPTION

The prism reference element is K = { 0 < x < 1 and 0 < y < 1-x and -1 < z < 1 }

NUMBERING

The orientation is such that triedra (01, 02, 03) is direct and all faces, see from exte‐ rior, are in the direct sens. References: P. L. Georges, "Generation automatique de mail‐ lages", page 24-, coll RMA, 16, Masson, 1994. z 3 ---- 5 ' | . | 4 . '| | | | | | | | | 0 . . .2 y | ' . 1 . ' x

IMPLEMENTATION

const size_t dimension = 3; const Float measure = 1; const size_t n_vertex = 6; const point vertex [n_vertex] = { point( 0, 0,-1 ), point( 1, 0,-1 ), point( 0, 1,-1 ), point( 0, 0, 1 ), point( 1, 0, 1 ), point( 0, 1, 1 ) }; const size_t n_face = 5; const size_t face [n_face][4] = { { 0, 2, 1, size_t(-1) }, { 3, 4, 5, size_t(-1) }, { 0, 1, 4, 3 }, { 1, 2, 5, 4 }, { 0, 3, 5, 2 } }; const size_t n_edge = 9; const size_t edge [n_edge][2] = { { 0, 1 }, { 1, 2 }, { 2, 0 }, { 0, 3 }, { 1, 4 }, { 2, 5 }, { 3, 4 }, { 4, 5 }, { 5, 3 } };
