The paper presents a numerical simulation on the interaction between focusing waves and a cylinder using a hybrid solver, qaleFOAM, which couples a fully nonlinear potential solver, QALE-FEM, with an incompressible two-phase Navier-Stokes solver, OpenFOAM, using the domain decomposition approach. In the qaleFOAM, the wave is generated using a piston wavemaker in a large domain governed by the QALE-FEM (FNPT domain), and propagates into a small sub-domain near the cylinder, in which the OpenFOAM is employed, before it enters the downstream of the FNPT domain and is effectively absorbed by a self-adaptive wavemaker at its end. Both the wave elevations and pressure on the cylinder surface are estimated and compared with the experimental data. Good agreement has been achieved. In addition, different numerical configurations have been attempted, aiming to examine the effects of the cylinder surface boundary condition and turbulence modelling for such cases.
