Dear all,

In my magnetic field, the world has global magnetic field zero and a cylinder in world has local magnetic field 3 Tesla along z-axis. When I run my programme, the verbose output as follows:

Then the program seems enter a infinite loop and did nothing (no exit, no killing loop).

Is anything wrong or should I setup some parameter to control the field?

Thank you.
