KW - Spectral methods on tetrahedra, rational basis functions, spectral accuracy.
AB - <p style="text-align: justify;">A spectral method using fully tensorial rational basis functions
on tetrahedron, obtained from the polynomials on the reference cube through
a collapsed coordinate transform, is proposed and analyzed. Theoretical and
numerical results show that the rational approximation is as accurate as the
polynomial approximation, but with a more effective implementation.</p>
