Hi Huiwen,
Thanks for keeping on trying! I opened an issue
https://gitlab.psi.ch/OPAL/src/issues/274
where we can track progress on getting your lattice file going.
Cheers,
Chris

Dear Andreas and Chris,
Hi. After referring to some sources and checking through possible errors
from my previous input, the same problem still persist. I really run out of
idea which part is going wrong right now.
Hereby I attached with the latest input file and the fieldmap for your
reference. I really look forward to any suggestion to solve this.
I sincerely appreciate your great help.
Thank you very much.
Best regards,
Huiwen

Dear Huiwen yes at the moment we are doing maintenance.
@Chris: you correct me, but I think to remember that you are not free
in defining the fast changing dimension when writing the field map. If so
this could maybe be the problem?
Cheers Andreas

Dear Chris,
Please find attached with the fieldmap from tosca. (I updated the latest
fieldmap)
For your information, gitlab.psi.ch/OPAL is currently running very slow
here. Not sure if the site is having maintenance or upgrade.
But I think I should have seen most of the SBEND3D examples given in the
OPAL/wiki, none of them reflects my current problem.
"This error turns up when OPAL can't turn the field map into a regular
grid. It can occur, for example, because of rounding errors when converting
to a polar coordinate system (so the grid spacing looks irregular)."
In this case, do you have any suggestion to solve this problem?
Thank you very much.
Best regards,
Huiwen

Hi Chris and Huiwen
maybe the fast changing column in the field map is the wrong one.
I guess the manual is not consistent with that.
@Chris: the update I send you hopefully fix that.
Cheers Andreas

Could you please send me a copy of the field map file if it isn't too big
(or put in on a drop box/equivalent if it is huge).
In case you didn't spot it, I would also like to draw your attention to
the SBEND3D-based example lattice here:

to me this looks like a unit problem. what are the units of your

Hi Huiwen please add also the std-output so we see how OPAL
read your field map file.

Subject: Fieldmap error using OPAL-CYCL

Dear Jochem Snuverink,
Hi.
I am a new phd in beam physics trying to use OPAL for my AVF-cyclotron
design.
I did my magnetic field study using OPERA3D, and would like to
investigate the AEO and tune results. However, when I try to execute the
input with parameters set using ringdefinition and sbend3d to read in the
fmap file, I received error message as follow:
Error> *** User error detected by function
"SectorMagneticFieldMap::IO::getInterpolator"
Error> Ran out of field points during read operation; check bounds
and ordering
It seems like the data size expected from the TOSCA file is different
from the real input. According to the manual, we do not have to input
anything else than the length and flux unit, so I thought the grid size of
the input is defined as given by the header of the tosca output file.
However, my prediction seem to be wrong.
Although I can convert the fmap format into other type, but this is the
most convenient way. I would greatly appreciate if you have any suggestions
to solve this problem.
Your soon reply is greatly appreciated.
Thank you very much.
Best regards,
Huiwen
