摘要： Plural of virtual curved surface solids, each of which is a curved surface solid formed by a combination of plural of virtual spheres, is placed so as to fill in space voxels, referring to porous-body data in which positional information is associated with voxel-type information (step S100). Information regarding a flow rate for each space voxel when a fluid passes through a porous body is derived by executing a fluid analysis based on the porous-body data (step S110). A flow-rate-weighted mean diameter Ru, which is a weighted average obtained by weighting an equivalent diameter R' i for each virtual curved surface solid with a volume V i and an average flow rate U i for each virtual curved surface solid, is derived based on information regarding the virtual curved surface solids and information regarding the flow rate for each space voxel (step S120).
