Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a structure analysis method for a rotary machine, capable of analyzing by exactly transmitting bending force generated in a blade to a disc. SOLUTION: A blade shape, constituted of a meridian planar shape of an impeller and a point group, is defined by a solid model by using a structure analysis program for preparing not a plate element but the meridian planar shape and the blade shape, the meridian plane shape and the blade shape of the solid model are automatically divided into a plurality of meshes, by using an automatic preparing program for a solid FEM data exclusive for the impeller, the meshes are analyzed structurally, and the result is displayed in images.
