Dear Hossein

I have updated the example 'cyclotronTune-2-1.in' at the wiki page. Note that I also had to modify the values of FMLOWE and FMHIGHE, because the units were changed since OPAL version 2.4 (see https://gitlab.psi.ch/OPAL/src/-/wikis/ReleaseNotes/OPAL-2.4)

Cheers

Pedro

Also, you have to update the beamline as:

L1:   LINE = (RingCycl)

Cheers,

Pedro

Dear Hossein

Try to run example 'cyclotronTune-2-1.in' from gitlab page https://gitlab.psi.ch/OPAL/src/-/wikis/Examples/cyclotron, in the section "Tune Calculation with OPAL's closed orbit finder". The example 'cyclotron1' has to be reviewed, because there are some issue related with it. So you must not use.

About the last bug that you reported: you cannot use RING as any element or variable name, because RING is an internal predefined attribute, so, you must change the name of cyclotron from:

Ring: CYCLOTRON, TYPE=RING, CYHARMON=6, PHIINIT=0.0, PRINIT=pr0, RINIT=r0, SYMMETRY=8.0, RFFREQ=f1, FMAPFN="bfield.dat", FMLOWE=72, FMHIGHE=590;

to 

RingCycl: CYCLOTRON, TYPE=RING, CYHARMON=6, PHIINIT=0.0, PRINIT=pr0, RINIT=r0, SYMMETRY=8.0, RFFREQ=f1, FMAPFN="bfield.dat", FMLOWE=72, FMHIGHE=590;

This solution must be work

I will update the input file in the wiki page and thanks for report it

Cheers

Pedro
