What type of energy (total mechanical energy, kinetic energy, etc.) is the energy that one sets for the primary particles?

Hi, considering the example B1, regarding a primary particle(for example: a muon; Energy = 1 GeV), What type of energy (total mechanical energy, kinetic energy, etc.) is the energy that one sets in PrimaryGeneratorAction.cc for the primary particles, both in SetParticleEnergy() as well as in the Geant4 user interface?, that is, is this energy the total mechanical energy?; Is it just the kinetic energy of the particle?. Is this energy the energy that is given by the relativistic momentum-energy relationship: E^2=m^2 c^4+p^2 c^2?. I hope you can help me.

In Geant4, you set the kinetic energy. The mass is determined by the particle type, and total energy and momentum magnitude are computed for you on demand (using the relativistic relationship).
