An analytical shell-model producing apparatus comprises a pair-surfaces acknowledging portion (107), a top/bottom side rib attribute acknowledging portion (107), an offset-surface producing portion (111), and an internal-surface producing portion (115). The pair-surfaces acknowledging portion (107) acknowledges as the pair-surfaces when the face-to-face distance of two (2) surfaces is equal or less than a reference-plate thickness size, which constitute the configuration model. The top/bottom side rib attribute acknowledging portion (109) acknowledges the pair-surfaces as to be either the top or the bottom side surface and the rib surface. The offset-surface producing portion (111) produces an offset-surface, by offsetting either the top or the bottom side surface and also the rip surface into an inside thereof. The internal-surface producing portion (115) registers the offset-surface seaming therebetween as to be an internal-surface model. |
