Numerical wave generation and absorption based on OpenFOAM

CHA Jing-jing,WAN De-cheng(State Key Laboratory of Ocean Engineering,School of Naval Architecture,Ocean and Civil Engineering,Shanghai Jiao Tong University,Shanghai 200240,China)  
Based on the interDyMFoam package in an open source code software-OpenFOAM,piston-type and flap-type numerical wave-makers are set up to generate linear wave and finite-amplitude waves,and the way of damping wave absorption is proposed.In order to absorb wave at the end of the wave tank,a damping zone funcuion is added to the solver.Several numerical experiments of the generation and absorption of linear wave and transient extreme wave in a numerical wave flume are performed to testify the effectiveness of the presented approach.
