| Hardware: | PC | ||
| OS: | Linux | ||
Can you please specify the system configuration you are using (Linux distribution, compiler version, libC, ...), and could you also provide us the exact input (macros or commands) fed to either exampleN02 and exampleN04 ? On Geant4 2.0, we cannot reproduce this problem using the standard input macros for testing on our Linux systems. *** This bug has been marked as a duplicate of 219 *** *** 'Gabriele.Cosmo@cern.ch' will be responsible for this bug. *** *** This bug has been marked as a duplicate of 221 *** *** 'John.Apostolakis@cern.ch' will be responsible for this bug. *** |
following the description in the manuals, or trying ExampleN02 or N04 leads always to similar errors: Warning (G4MagIntegratorDriver): The stepsize for the next iteration=2.27097e-22 is too small - in Step number 1. Requested step size was 100.151 . Previous step size was 100.151 .
