| Abstract: | A recognition approach to a two-dimension finite element mesh drawings is presented. A mesh drawing is scanned and made into binary image. Then, nodes and links, two kinds of primitives ,are recognized from the drawing. Based on the topological property of the two kinds of primitives, a symmetrical adjacent matrix is generated. Line degree is taken for limitative condition for the recognition of elements which is advanced on the upper triangular matrix of A. At last , nodes coordinate and express data of elements which interfaces with application program are generated. |
