Simulating different particle gun energies in a single run

some inspiration: void myRunAction::BeginOfRunAction(const G4Run* aRun) { G4AnalysisManager* analysisManager = G4AnalysisManager::Instance(); char fileName[65]; sprintf(fileName, "Somethingsomething_run%04d",aRun->GetRunID()); analysisManager->SetFileName(G4String(fileName)); analysisManager->OpenFile(); }

hope that is thread safe
