We present high fidelity numerical simulation of two-frequency vibrations on a silicone fluid bath. Two-frequency parametric vibrations excite two competing unstable wave modes. These wave modes superpose to form quasicrystalline structures. Our DNS results will allow us to analyse the superposition of the competing wave modes and the role of viscous dissipation.
