Wave uplift pressure on horizontal platforms

An analysis is presented to investigate aspects of wave hydrodynamic effects on a horizontal platform by numerical methods. A finite element procedure is developed to model the fluid region. The flow is assumed to be inviscid and irrotational. The two dimensional model treats the full non-linear free surface equations along with Laplace equation. In this model, the physical domain is subdivided into segments. The hydrodynamic equations of motion for each segment are independently mapped using isoparametric procedure, into an assemblage of mathematical planes of simple geometry. Finite element modelling is done in the sequence of mathematical planes.
