Abstract: Porous body data 60 in which position information and type information are correlated is reference to take a curved surface solid including a parent virtual sphere and child virtual spheres as a virtual curved surface solid, and place multiple virtual curved surface solids so as to fill in space pixels with curved surface solid pixels occupied by virtual curved surface solids (steps S230 through S320). Repeating this process, by placing multiple virtual curved surface solids within space in a porous body, the microstructure of the porous body is analyzed precisely. As for analysis, deriving of in-plane uniformity index γx, spatial uniformity index γ, pressure drop P, flow-through velocity T, and equivalent diameter d for example, and acceptability determination based on derived values thereof, is performed.

Abstract: A method for analyzing a microstructure of a porous body is, for example, a method using porous-body data in which positional information providing a position of a voxel of a porous body obtained by three-dimensional scanning is associated with voxel type information including information that allows determination as to whether the voxel is a spatial voxel representing a space or an object voxel representing an object. This method includes (a) a step of defining an imaginary surface that is in contact with at least one object voxel present on a surface of the porous body, and identifying, as opening-related voxels, spatial voxels that are in contact with the imaginary surface and spatial voxels that continuously lie in a linear direction from the imaginary surface; and (b) a step of analyzing a microstructure of the porous body on a basis of the opening-related voxels.
