OPAL-T can track particles through bends that bend more than 90 degrees. But it doesn't expect a quadruple to bend. However when you place the elements manually in 3D it should work.
Could you send me your input file, then I can try to find out what goes wrong.

Subject: tracking through alpha magnet
Date: 8 April 2020 at 23:17:51 CEST
after about three weeks of learning the code I really enjoyed it.I am trying to track an electron beam through an alpha magnetwhich has a field similar to one of a half of a quadrupole.I used a long qudarupole element supplied by Opal, turned it around y-axes
and shifted by some distance away from the x-axes. The beam is supposed to make a full turnin the magnet and exit it at around 270-degrees. I monitor the reference trajectory in x,z plane.It seem like the trajectory behaves well for the first half of the loop but then instead of completing
the turn, the reference particle suddenly makes a very quick move which is unphysical.Could you please comment if I can simulate such a motion in Opal-t? Basically, the question is can I simulateturns with any arbitrary angle >90-degrees?
I would appreciate any comment.Thank you in advance
