There is an increased drive in solving complex ship and offshore hydrodynamic problems using viscous flow computations. Reliable seakeeping computations demands for accurate generation of waves. Present work demonstrates the simulation of numerical wave tank capable of generating regular and irregular waves with forward speed and current effects. Waves are generated according to velocity inlet method using a homogeneous multiphase flow model. The forward speed effects are accounted as an equivalent current. The main emphasize of present work is to generate and validate irregular waves; irregular waves are generated according to JONSWAP spectrum. The free surface elevations and sea spectrum are evaluated against theoretical computations. Treatment of outlet boundary condition and domain initialization is discussed.
