Hi! As i wrote in header i would like to find second electrons which is moved from one volume to another. I do the following;

void SteppingAction:UserSteppingAction(const G4Step* step){
//0 - not secondary, 1 - secondary, 2 - not electron
unsigned secon = 2;
if( step->GetTrack()->GetDynamicParticle()->GetDefinition()-.GetParticleName() == "e-"){
           if(step->GetTrack()->GetParentID() != 0) secon = 1;
           else secon = 0;
}
//0 - not penetrated, 1 - penetrated
unsigned penet = 0;

if(step->GetTrack()->GetVolume()->GetName() != step->GetTrack()->GetNextVolume()->GetName()){
        penet=1;
}

However when i chek output i dont get any penet = 1. When i have been trying to print names of this and next volumes, i recive the same names. How to find next Volume properly?
