Calculation of the calorific value of the material

Dear teachers and MS technical engineers in the community, 

I have been using MS software for nearly eight years, and recently encountered a problem in the process of using, which module of MS software should be used to calculate the calorific value of materials? I have been looking up information without relevant detailed steps, but also hope that the experts are generous, the more detailed the better, because I am very stupid, thank you!

Good luck,

YunLiu MU.
