Hi all, In my simulation I have optical photons with energy of 2.92 eV. When I use: particleGun->SetParticleEnergy(2.92*eV), and then particleGun->SetParticleMomentumDirection(G4ThreeVector(x,y,z)) with, for example, x=0, y=0, z=1, everything goes fine, but when I change x, y, z into the random numbers, I get: Warning: G4MaterialPropertyVector::GetProperty ==> attempt to Retrieve Property above range Can anyone explain me, why I get this message when random numbers are introduced? Does it change the energy of the optical photon? Is there a range of allowed/forbidden energies? If yes, how can I control it? Thanks, Aivaras
