Can Geant4 simulate Heat?; If not, how likely is that a future release of Geant4 will add it to the Geant4 toolkit in the near future?. Thanks
No and not. Geant4 is a “single particle” Monte Carlo simulation. It tracks individual particles based on their point-like interactions with material atoms/nuclei/electrons. Thermal modelling is much better modelled by something like COMSOL.
Ok, thank you very much for your help. I'll keep it in mind.
