WebbThe property that each of the basis functions is 1 at its associated vertex, and 0 at the other three vertices means that the set of basis functions is a Lagrange interpolation basis for the vertices. Using our basis function notation, the solution to the interpolation problem has the very nice form: f(x;y;z) = fa˚ a(x;y;z) + fb˚ b(x;y;z) + fc˚ WebbA hexahedron is a polyhedron with six faces, eight corners and twelve edges or sides.
