PURPOSE: To provide a flow analysis device capable of reducing calculation time and required man-hour by using the result of a coarsely analyzed object and space in the calculation of dense meshes whose object is the partial area. CONSTITUTION: A plural mesh condition input part 12 is provided with a routine mesh storage part 121 and a routine mesh separately prepared beforehand is stored in the routine mesh storage part 121. The input part 13 of an external condition and a material condition, etc., is provided with the storage part 131 of a routine boundary condition or the like. Heat generation uniformly determined corresponding to the kind of an equipment to be the object of detalied analysis and an initial value at the time of repetitive calculation, etc., are turned to a set with the identification code of the partial area, inputted beforehand and stored in the storage part 131 of the routine boundary condition or the like. For the coarsely meshed entire area and the densely meshed partial area, the halfway results of the calculation of the respective areas are used as the initial value and a boundary condition at the time of the calculation of the other area and the repetitive calculation, the man-hour and the calculation time are saved and execution is highly accurately performed for both areas. |
