Hello Norman, please check the manual at 7.7.1 and figure 4.3 on page 55.

Here an example of an SBEND:

AND1:SBEND, L=0.614, ELEMEDGE=58.18470+0.023, ALPHA=15.0, K0=-17.757/10, FMAPFN='FAND1.T7', DESIGNENERGY=72.0, EXITANGLE=-35.0;

FAND1.T7:

1DProfile1 5 5 2.0

-8.1333   -2.1333    3.8667 1

55.5161   62.8408   70.1654 1

-0.0170

0.0966

-0.017

1.8055

-0.2819

0.5680

0.3817

0.0966

the corresponding Transport element would look like:

16. 7.0 .0;

16. 8.0 .0;

20. 180.0;

2. 15.0;

4.   .3070 25.0 .0 /AND1/;

4.   .3070 25.0 .0;

2. 0.0;

20. -180.0;

Cheers Andreas 

PS: can you give me an update on your work?
