How to set minimum time step limits using TimeSteppingManager.
1 - GEOMETRY DEFINITION
It is a simple box which represents a 'semi infinite' homogeneous medium.
Two parameters define the geometry :
- the material of the box,
- the full size of the box.
The default geometry is constructed in DetectorConstruction class.
2 - PHYSICS LIST
PhysicsList is Geant4 modular physics list using G4EmDNAPhysics &
G4EmDNAChemistry constructors.
3 - AN EVENT: THE PRIMARY GENERATOR
The primary kinematic consists of a single particle starting at the center of
the box. The type of the particle and its energy are set in the
PrimaryGeneratorAction class, and can be changed via the G4 build-in commands
of G4ParticleGun class.
The chemistry module is triggered in the StackingAction class when all
physical tracks have been processed.
4 - OUTPUT
Physics initialization and the defined reaction table are printed.
G4ITStepManager processes the chemical stage time step after time step.
Chemical reactions are printed.
