Abstract
Solution of the wave agitation problem through a variational solution of the Helmoltz equation V. Bovolin, A. Fortunate & E.P. Carratelli Department of Civil Engineering Email: Eugliese@Bridge. diima. unisa. it Introduction Wave agitation problem on constant depth is governed by the well known Helmoltz equations. There is no shortage of academic or commercially available finite elements or finite difference software to solve such an equation; there are however a number of simple geometrical configurations where the computational requirements and the data preparation effort involved in running complex codes are out of proportion in comparison with the objective. Such problems are often found when carrying out feasibility studies for small harbours or coastal protection works. A Helmoltz equation solver based on a non-discretised version of Ritz's variational method was developed and tested to provide a fast and efficient tools for rectangular water basins. After validati
