Reasons for using JSS2
There is no environment to perform the satellite thermal analyses of numerous samples under realistic time.
Achievements of the Year
We developed an method to create emulator for satellite thermal simulator using the Gauss process regression. The method was applied to actual satellite thermal problems, and the effectiveness was shown. JSS 2 was employed to study the speedup of calculation of the Gaussian process regression.
