A method for generating a two-dimensional mesh model of an object made up of a finite number of elements and provided with nodes is disclosed. Data about an original contour of the analysis object, including data about contour nodes are defined. The original contour is transformed by scaling up or down only in the direction of a predetermined first axis at a predetermined first scaling factor to obtain the transformed contour. Based on the contour nodes and additional nodes defined on the transformed contour, a primary mesh model whose contour is the same as the transformed contour is generated. By scaling the primary mesh model only in the direction of the first axis at a second scaling factor equal to the reciprocal of the first scaling factor, a secondary mesh model whose contour is the same as the original contour is generated.
