THE ALGORITHM FOR AUTOMATIC GENERATION OF FINITE ELEMENT MESH

This paper presents the methods for automatic generating of the element node topology matrix (ENTM) and automatic assembling the whole node topology matrix (WNTM) on the basis of the topology analysisof finite element mesh. The algorithms of automatic generating and automatic assembling are given. The methods implement the full automatic generation procedure of 2D and 3D finite element mesh andprovide the basis for analyzing relativity of elements and nodes.
