Free surface simulation of a two-layer fluid by boundary element method
International Journal of Naval Architecture and Ocean Engineering, 2010 A two-layer fluid with free surface is simulated in the time domain by a two-dimensional potential-based Numerical Wave Tank (NWT). The developed NWT is based on the boundary element method and a leap-frog time integration scheme.
