Hi - I am having trouble with N04 - charged particle trajectories do not curve as a result of the magnetic field.
The only changes i made were to comment out the calorimeter, and to change to particle gun event generation, where I throw 0.3 GeV mu+. the default field is 3 Tesla, so these tracks should loop, but they are quite straight, except for some small wiggles due to multiple scattering.
I put a cout in ExN04Field::GetFieldValue, and i see that this routine is being called as the particles are being tracked.
If i change the particle i'm throwing to a chargedgeantino, the tracks loop in the field as expected.
Any suggestions? bill
p.s. geant4 version 9.6, OSX 10.7.5
