Numerical analysis data creating method and apparatus, and computer-readable program

Abstract

A numerical analysis data creating method creates numerical analysis data that are obtained by analyzing an analyzing target. The method judges whether or not to create the numerical analysis data of the analyzing target using data that have been stored in a database part, searches the database part based on information related to the analyzing target and displaying a search result if the numerical analysis data of the analyzing target are to be created using the stored data, and creates and stores in the database part the numerical analysis data of the analyzing target by modifying usable data if necessary, when the usable data exist in the search result. The data that have been stored in the database part include numerical analysis data, analysis model data, material characteristic data and attribute data with respect to targets that have been analyzed.
