Claim:
1. An analysis supporting method of calculating a variation in at least one of a total pressure loss coefficient and a total material cost when an attribute value of an assembly through which fluid is to flow is varied, using a response surface, the method comprising: causing an analysis supporting apparatus including a processing section having an input processing unit, an analysis control unit, a connection information generating unit, a response surface generating unit, an objective function value calculating unit, and a display processing unit, as well as a database, an input system, and a display section, to: divide, with said connection information generating unit, shape data of the assembly through which fluid is to flow, which is an analysis target, into a plurality of divided shape data items at a connection boundary set via the input system when an objective attribute value is set, with the input system, as at least one of a total pressure loss coefficient and a total material cost, and a function regarding the at least one of the total pressure loss coefficient and the total material cost is set, with the input system, as an objective function; set, with the input system, a predetermined divided shape data item as a first divided shape data item among the plurality of divided shape data items, set, with the input system, a divided shape data item adjacent to the first divided shape data item as a second divided shape data item, and set, with the input system, a divided shape data item, which is adjacent to the second divided shape data item and is different from the first divided shape data item as a third divided shape data item; calculate, with the objective function value calculating unit, a first inlet dynamic pressure obtained by parameterizing an objective function in the first divided shape data item and a distribution parameter obtained by parameterizing a distribution of attribute values at the connection boundary, so as to parameterize, with the response surface generating unit, a response surface in the first divided shape data item; calculate, with the objective function value calculating unit, a second inlet dynamic pressure in the second divided shape data item based on the distribution parameter and the first inlet dynamic pressure in the first divided shape data item, and calculate a distribution parameter at the connection boundary between the second divided shape data item and the third divided shape data item based on the distribution parameter and the first inlet dynamic pressure in the first divided shape data item, so as to parameterize, with the response surface generating unit, a response surface in the second divided shape data item; and calculate, with the objective function value calculating unit, at least one of the total pressure loss coefficient and the total material cost based on the respective inlet dynamic pressure in each divided shape data item; and optimize a design of the assembly through which the fluid is to flow based on the at least one of the total pressure loss coefficient and the total material cost.
