Abstract
A mesh number prediction method obtains a mesh length for a case in which a mesh having an arbitrary shape is created by approximating an entire analyzing target by a three-dimensional (3D) mesh model based on data of a 3D surface model of the analyzing target, obtains a mesh number of each part forming the analyzing target for a case in which a mesh having an arbitrary shape is created by approximating each part by a 3D mesh model based on the mesh length, and obtains a predicted total mesh number of the entire analyzing target from a ratio of volumes of the entire analyzing target and each part based on the mesh number.
