Dear all,

Can someone please explain how 3DMagnetostatic fields can be implemented
(by the way can they be implemented in OPAL-t yet?).

E.g. I have this fieldmap of a quadrupole:

cst2opal_quad_1Ax_xyz_rough.t7

# Origin: cst_quad_1Ax_xyz_rough
# x,y,z in cm
# Bx,By,Bz in T
3DMagnetoStatic
-1.500 1.500 60
-1.500 1.500 60
-10.000 10.000 400
-2.56903e-05 3.9909599999999996e-07 1.26009e-05
-2.61039e-05 4.04632e-07 1.27818e-05
....

I tried using
QP1: Quadrupole, L=0.05, ELEMEDGE=0.5,
     FMAPFN="cst2opal_quad_1Ax_xyz_rough.t7", K1=0.1;
  
But despite the example entry in the wiki
(https://gitlab.psi.ch/OPAL/manual-master/wikis/elements) the quadrupole-element does not have a FMAPFN attribute.

Thank you very much in advance.

Best regards,
Simon
