Abstract: A thermal analysis method and apparatus, and a computer program that enable highly accurate heat transfer simulation of a structure or space, while reducing calculation costs. By performing thermal analysis on a structure or space using the calculation meshes generated by initial dividing means, the spatial distribution of heat flux vectors J and temperature gradient vectors ∇T are calculated; by calculating the volume integrals of the inner products J·∇T of the heat flux vectors J and the temperature gradient vectors ∇T for individual partitioned regions and acquiring the absolute values of the volume integrals, thermal management sensitivity indices are calculated for the partitioned regions. Subsequently, partition of calculation meshes and subdivision of partitioned regions are performed on a predetermined number of partitioned regions that indicate greater indices among the calculated thermal management sensitivity indices, for example one partitioned region. Thermal analysis is performed again using the calculation meshes.
