Flowchart of the conceptual logic of the proton transport in the pMMC method. Adaptive choice of slab size is performed (environment slab size restriction) and the macro step parameters are sampled from the database. The proton is transported (proton tracking) and deposits the sampled energy loss. If a hard interaction (elastic or inelastic hadronic interaction) was sampled (Process?), secondary protons and neutrons are transported and heavy ions deposit their energy locally
