Abstract

Abstract

The elliptic mild-slope equation for linear water waves is an effective mathematic model for studying the water wave propagating in coastal mild-slope zones.The finite volume method on a unstructured grid system is adaptive well to complicated boundaries, and keeps conservation during the it erative calculation.The numerical model for the elliptic mild-slope equation on the unstr uctured grid is presented.In the presented model, the elliptic mild-slope equation is discredited based on the finite volume method on the unstructured grid, and the GPBiCG (m, n) algorithm is applied to solve the discredited equation.It is shown that the presented numerical model can be applicable to simulating the coastal wave propagation in complicated boundary conditions effectively.
