Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

In in your main instead of one line runManager->SetUserInitialization(new LHEP()); insert more lines: G4double myCut = 0.1*mm; LHEP* pLHEP = new LHEP(); pLHEP->SetDefaultCutValue(myCut); runManager->SetUserInitialization(pLHEP); VI
