Dear John, I am beginning to understand Geant4's transportation process. GetFieldValue() is used to solve a particle's equation of motion in the field by each step. Geant4 handles particle's trajectory, comparing the solved equation with some points (e.g. initial-position, mid-position and endpoint). > So if you add a print method in your field, and set > /tracking/verbose 1 > you will see that the field is called several times for a typical step. I set a command you say, I could check steps. Thank you for your help. Best Reagrds, Kayo Matsuura
