An important but not yet well-understood mechanism during the growth of defect-free quasicrystals is the repair of defects or excitations via phasonic flips. We simulate a one-component quasicrystals in order to study the growth and the influence of phasonic flips. We developed a Monte Carlo method to fathom the growth of quasicrystals without and with phasonic flips. To speed up the simulations, the possible directions of the growth are limited to positions given by fixed vectors. For the calculation of the energy, and therefore for the probability of occupation of a position, an oscillating pair potential is used. First results show the formation of structures with 10-fold rotational symmetry for low temperatures without phasonic flips. In the next step, phasonic flips are taken into account in order to reveal how they influence the growth of quasicrystals.
