The present method is a method for executing a computational fluid analysis on a blood flow in a computation object region, and displaying the analysis results, comprising the steps of: obtaining, by a computer, blood vessel shape data extracted from medical images causing, by the computer, a user to specify a computation object region from the blood vessel shape data retrieving, by the computer, a template according to the specified computation object region, wherein the template stores computation conditions validated for a blood flow analysis of the specified computation object region and executing, by the computer, the computational fluid analysis of the blood flow in the computation object region by applying the computation conditions to the blood vessel shape data, and outputting the analysis results.
