A stray field element with local and global components. Global components are defined relative to the
initial beamline direction.
Parallel capable? : yes
GPU capable? : no
Back-tracking capable? : no
Optionally used to assign an element to a group, with a user-defined name. Group names will appear in the parameter output file in the column ElementGroup
This element simulates stray fields. These fields are considered perturbations, in that they change the trajectory (or orbit), but not the floor coordinates. Local stray fields (LBX and LBY) are referenced to the local coordinate system. Global stray fields (GBX, GBY, GBZ) are referenced to the global coordinate system, which coincides with the local coordinate system only at the start of the beamline (unless there is no bending, in which case the two systems are identical).
