The present invention relates to a method for efficiently processing an inclined boundary in a finite element model using a mild-slope equation based on a numerical technique. The present invention provides the method for processing the inclined boundary in the finite element model using the mild-slope equation, which, in order to solve shortcomings that processing a boundary in a boundary surface inclined in a vertical direction is not easy in a case that a governing equation used in the finite element model is an elliptic differential equation in the conventional method, may properly process the inclined boundary based on two conditions that a long wave condition is always satisfied near the boundary because the depth of water becomes zero in the inclined boundary and a solution of a linear long wave may be expressed with the Bessel function in a case of having a regular inclination. |
