ABSTRACT:
A method forms an analyzing model for use in finite element method analysis. The method includes the steps of (a) detecting faces of elements of the analyzing model which do not make contact with faces of other elements, based on information related to the analyzing model which is used in the finite element method analysis and describes a target unit which is to be analyzed, (b) grouping the faces of the elements detected in said step (a) into first groups for each of face numbers which are assigned with respect to each of the faces for the sake of convenience, (c) out of the elements having the faces included in each of the first groups obtained in said step (b), extracting elements having element numbers with the same increase number and grouping the extracted elements in second groups, where the element numbers are assigned with respect to each of the elements for the sake of convenience, (d) storing storage information with respect to the elements included in each of the second groups obtained in said step (c), where said storage information includes an element initial number, an element final number, an element number increase value and a face number included in the element, (e) specifying a range of the faces formed by the elements extracted in said step (c) with respect to said storage information, (f) newly forming solid finite elements in a space which is formed by the faces in the range specified by said step (e), (g) forming information which defines boundary conditions at faces outside the range specified by said step (e), and (h) changing conditions values depending on position coordinates of the faces in the definition of said boundary conditions of the faces.
