A Review of Strategies for Finite Element Modeling of Three Dimensional Hydrodynamic Systems
The methodology for three dimensional finite element analysis of hydrodynamic systems has been readily available since the basic development of two dimensional models. However, the simulation of a system composed entirely of three dimensional elements is computationally very expensive and little practical analysis has been undertaken. In an effort to reduce cost the author in a previous paper presented a simplified three dimensional model that used the hydrostatic pressure approximation to eliminate the vertical momentum equation and a transformation of the geometric system to a unit vertical dimension to directly solve for the free surface profile (King, 1982).
