四、論壇XXz物理好資源網(wǎng)(原物理ok網(wǎng))

峰會(huì)是一個(gè)開(kāi)放的社區(qū)，任何人都可以在這兒提出問(wèn)題、分享經(jīng)驗(yàn)和知識(shí)。峰會(huì)上有好多關(guān)于的討論和技術(shù)支持，對(duì)于菜鳥和中級(jí)用戶都很有用。XXz物理好資源網(wǎng)(原物理ok網(wǎng))

以下是峰會(huì)上的一個(gè)問(wèn)題，關(guān)于怎么使用模擬一個(gè)粒子在材料中的運(yùn)動(dòng)軌跡：XXz物理好資源網(wǎng)(原物理ok網(wǎng))

// Use the Geant4 tracking manager to initialize the track
G4Track* track = new G4Track(new G4DynamicParticle(G4Proton::Proton(), G4ThreeVector(0.,0.,500.*MeV), 0.), 0., 0.);
G4TrackingManager* trackingManager = G4EventManager::GetEventManager()->GetTrackingManager();
trackingManager->SetStoreTrajectory(true);
trackingManager->SetTrajectory(new G4Trajectory(track));
trackingManager->ProcessOneTrack(track);
// Get the trajectory from the track and store it in a file
G4Trajectory* trajectory = (G4Trajectory*) track->GetUserInformation();
std::ofstream outFile("trajectory.txt");
for(int i=0; iGetPointEntries(); i++) {
    G4TrajectoryPoint* point = (G4TrajectoryPoint*) trajectory->GetPoint(i);
    outFile << point->GetPosition().x()/mm << " " << point->GetPosition().y()/mm << " " << point->GetPosition().z()/mm << std::endl;
}
outFile.close();

五、有時(shí)間概念嗎？XXz物理好資源網(wǎng)(原物理ok網(wǎng))

支持時(shí)間模擬，可以記錄粒子在模擬中經(jīng)過(guò)的時(shí)間和抵達(dá)某個(gè)特定地點(diǎn)的時(shí)間。這對(duì)于個(gè)別應(yīng)用場(chǎng)合十分重要，比如核醫(yī)學(xué)和粒子化學(xué)學(xué)中的時(shí)間幀率。XXz物理好資源網(wǎng)(原物理ok網(wǎng))
