There are now many nodal superconductors in heavy-fermion (HF) systems, charge-conjugated organic metals, high- cuprates and ruthenates. On the other hand, only few of them have well established . We present here a study of the angular-dependent thermal conductivity in the vortex state of some of the nodal superconductors. We hope it will help to identify the nodal directions in of , , and .
