in my code I have the following lines :
G4PrimaryParticle* particle = new G4PrimaryParticle();
FDsimG4StoreHit* G4Particle = theFDSimulator->GetG4Particle();
G4ThreeVector momentum = G4ThreeVector(G4Particle->GetDirX(), G4Particle->GetDirY(), G4Particle->GetDirZ()); momentum = momentum*(G4Particle->GetEnergy()*eV);
particle->SetMomentum(momentum.x(),momentum.y(),momentum.z()); cout<<particle->GetPx()<<" "<<particle->GetPy()<<" "<<particle->GetPz()<<endl;
and the print message reports exactly the momentum components.
When I pass this code to the Geant version 4.9.6 particle->GetPx(), particle->GetPy() and particle->GetPz() return different values and a different total momentum. How can I set the different components to obtain the right energy for the simulated particles?
There are changes in this method? Thanks
