Question Problem with gps 

Forum: Particles
Date: 17 Dec, 2012
From: Tuoyu Cao <Tuoyu Cao>

Hi,

I am doing a simulation based on extend/electromagnetic/TestEm5. I need to build a source with certain distribution so I want to use gps. According to its mannual, I can simply replace G4ParticleGun with G4GeneralParticleSource. However it does not work. G4GeneralParticleSource class does not have SetParticleMomentumDirection and SetParticleEnergy function and it does not accept "particleGun = new G4GeneralParticleSource(G4 int)". I just command the first two functions and use "particleGun = new G4GeneralParticleSource()". The program can compile but when I do "ls /gps" in the macro, only "/gps/ang" exists and I cannot use other gps commands. Thanks a lot for any help.

Regards Tuoyu
