摘要： PROBLEM TO BE SOLVED: To provide an analytical shell model creation apparatus which can easily create an analytical shell model as a geometric model which has not been considered by conventional art.
SOLUTION: A pair-surfaces recognizing part 107 recognizes two arbitrary surfaces which constitute a geometric model and have a face-to-face distance equal to or less than a reference-plate thickness size inputted by a reference-plate thickness designating part 105. A top/bottom rib attribute recognizing part 109 recognizes the pair-surfaces as a top side surface, a bottom side surface and a rib surface. An offset-surface creation part 111 creates an offset-surface, by offsetting a surface group of either the top or the bottom side surfaces and the rib surface into the normal direction of internal direction of each shape thereof. An intermediate surface model producing part 115 registers the offset-surface seaming therebetween as an intermediate surface model.

摘要： PROBLEM TO BE SOLVED: To provide a shape model simplifying device that efficiently simplifies partial shapes unnecessary for an analysis of a shape model to be analyzed, since the shape model strictly expresses a product shape while including many partial shapes that do not affect the accuracy of the analysis.
SOLUTION: A means 109 for automatically extracting candidate parts for simplification creates a shape that is enlarged by a reference parameter 105 relative to shape model data 103 in the outward direction of the shape model, and another shape that is contracted by the reference parameter 105 in the inward direction of the shape model; compares the enlarged shape with the shape model; compares the contracted model with the shape model; searches for an eliminated partial shape and an inverted partial shape; and uses the partial shape that matched search requirements as data 111 on the shapes of candidates for simplification. Thus, either by inputting the reference parameter 105 for simplification or by simply selecting simplification data from a simplification database 107, shapes unnecessary for analysis are automatically extracted and a shape model for analysis can be efficiently created, even for shape models without feature information.
