A method of creating an analysis model includes the steps of storing first shape information in association with instruction information that is used for creating the analysis model and that includes shape feature information about a connecting part in the first shape information; comparing second shape information with the first shape information associated with the instruction information; determining whether a difference between the first shape information and the second shape information is within an allowable range for the shape feature information included in the instruction information; and setting the instruction information if the difference between the first shape information and the second shape information is within the allowable range.
