Dear Peter, I checked the programs that read the field values - they are OK. I also tried to set the uniform magnetic field - still problems. The method GetFieldValue is really called at each step. I checked that it gives the correct field values at the initialization stage - everything looks fine. The problem is that the same method gives absolutely wrong (zero) values during tracking. I would be glad if you would have a look on the code and the log file (MuCatcher.out). You would see that there is a difference between the field values at the initialization (line 167) and tracking (start from line 440). Sorry, the code is a bit large but the part related to the field is based on the field04 example. The link to the code: http://people.web.psi.ch/kiselev/G4/MuCatcher.tar.gz Thank you in advance, Oleg Kiselev. -----Ursprüngliche Nachricht----- Von: Gumplinger Peter [mailto:firstname.lastname@example.org] Gesendet: Donnerstag, 29.

Also, field04 is maybe the most complicated example you could start from when all you want is one field for the entire simulation world. I think for the mechanics of how to attach a global field to the 'world', the field01 example would suffice. ------------------------------------------------------------- Visit this GEANT4 at hypernews.slac.stanford.edu message (to reply or unsubscribe) at: http://hypernews.slac.stanford.edu/HyperNews/geant4/get/emfields/169/1.html
