Finite element analysis of two-dimensional non-linear transient water waves
Guoxiong Wu,R. Eatock Taylor +1 more
TL;DR: In this article, two approaches are used to analyze the two-dimensional nonlinear time domain free surface flow problem by the finite element method, one is based on the velocity potential which is approximated by means of shape functions, and the other approach is to write both potential and velocity in terms of the shape functions at the same time.
