| Abstract: | Two-dimensional triangular grids and three-dimensional tetrahedral grids were applied in the model.The finite volume method was used to discrete the integral form of the governing equations.Since these integral equations can be solved numerically by flux calculation over an arbitrarily-sized triangular mesh,the finite-volume approach is better suited to guarantee mass conservation in both the individual control element and the entire computational domain.The model computes the tide level as the external mod... |
