摘要： Object information representing a honeycomb structure with a plurality of meshes is obtained, and an inner-wall-surface heat transfer coefficient hs, i.e., a heat transfer coefficient between an inner wall surface of a cell and a fluid, is derived as follows. First, one of the meshes as a target for derivation of the inner-wall-surface heat transfer coefficient hs is set (S200), and a dimensionless coordinate X* is derived on the basis of position information (X-coordinate) of the set mesh and fluid state information (S210). An inner-wall-surface dimensionless heat transfer coefficient Nus corresponding to the derived dimensionless coordinate X* is then derived on the basis of the inner-wall-surface dimensionless correspondence information (S220 to S250). The inner-wall-surface heat transfer coefficient hs in the mesh set as the derivation target is then derived on the basis of the derived inner-wall-surface dimensionless heat transfer coefficient Nus (S260).
