Finite element solution of free-surface ship-wave problems

An unstructured finite element solver to evaluate the ship-wave problem is presented. The scheme uses a non-structured finite element algorithm for th e Euler or Navier-Stokes flow as for the free-surface boundary problem. The incompressible flow equations are solved via a fractional step method wher eas the non-linear free-surface equation is solved via a reference surface which allows fixed and moving meshes. A new nonstructured stabilized approx imation is used to eliminate spurious numerical oscillations of the free su rface. Copyright (C) 1999 John Wiley & Sons, Ltd.
