Vortex and wake induced vibrations (VIV/WIV) of a circular cylinder at low values of the Reynolds number (Re) are simulated by means of a fully coupled fluid-structure interaction numerical model based on the finite element method. It is shown that VIV/WIV could occur far below the first Hopf bifurcation (Re <47). The main objective of this study is to determine the limiting Reynolds-Reduced velocity (Ur) curve that separates the non-vibrational area from the possible vibrations occurrence area. We assume that by taking a zero mass cylinder and zero structural damping we will obtain the low limit of vibrations in terms of Re and Ur. It is shown in particular that transverse vibrations could occur for reduced velocities larger than 40 and not below 3.5.
