Abstract
By numerical relaxation with interatomic pair potentials, we study the stability of quasicrystalline models. A monoatomic model and a AlMnSi model are found stable and we present their partial pair distribution functions. These quasicrystalline structures are described by 3D cross sections through 3D atomic motifs in a 6D space. During the relaxation, atoms move from their initial positions and we show that these displacements correspond to modifications of the atomic motifs
