PURPOSE: To shorten model generating time in the analysis of a structure consisting of plural materials by attaching a consecutive number on a node number and an element number in the same area.
CONSTITUTION: A graphic 10 required for the model of the structure is inputted, and all the closed areas 11-14 in the graphic 10 are automatically recognized, and figure B is formed by drawing an element parting line on the graphic 10, and the area is selected, and the physical property value of the area, for example, the Young's modulus is inputted. A part in accordance with an undefined node or element is designated, and a condition for the part, for example, a constraint condition or load attaching condition is inputted, and the intersection of the element parting line in each area is automatically set as the node, and the consecutive number is attached, and a small area enclosed with the node is set as an element, then, the consecutive number is attached. Furthermore, a format is converted into the one requested by a finite element analysis program by automatically combining the data of the physical property value, the condition, the node, and the element.
