Patent ID: 8306792

Claim:
A simulation device for thermal radiation energy, comprising: three-dimensional data acquiring means for acquiring three-dimensional space data obtained by defining a three-dimensional space by means of a plurality of grids, the three-dimensional space data containing a plurality of three-dimensional objects; form factor calculating means for calculating a form factor for each combination of two arbitrary grids of the plurality of grids; grid attribute data acquiring means for acquiring an area, a reflectance, and a temperature of each grid; thermal radiation energy calculating means for calculating, as thermal radiation energy of each grid, based on the area of each grid, the form factor, the reflectance of each grid, and the temperature of each grid, a sum of thermal radiation energy emitted from each grid and thermal radiation energy obtained through reflection of a thermal radiation ray emitted from each grid; and output means for outputting a calculation result for the thermal radiation energy of each grid to an output device.
