Hi Sherlp,

I think this is what you want

https://gitlab.psi.ch/OPAL/src/-/blob/master/src/Classic/Algorithms/PartBunchBase.hpp#L504

This is the function where the origin and mesh size of the computational domain are set and it is called from ParallelTTracker.cpp and ParallelCyclotronTracker.cpp. Hope it helps.

Hi Sheryl, I am not sure I see what you want to accomplish.

Maybe it is easier to have a short Zoom. Let me know your

availability.

Cheers Andy

Dear A

I 'm sorry for my ambiguous statement. And I found a precise one below (14.6
Bounding Box Enlargement)

https://gitlab.psi.ch/OPAL/documentation/manual/blob/master/fieldsolvers.asciidoc#sec.fieldsolvers.FSBBOX

I would like to find where to create the bounding box in the source code.
According to your answer of setting up the computational domain in
setupFieldsolver(), I have found two possible location which mentioned domain
and mesh spacing below:

https://gitlab.psi.ch/OPAL/src/-/blob/master/src/Structure/FieldSolver.cpp#L422

https://gitlab.psi.ch/OPAL/src/-/blob/master/src/Solvers/FFTPoissonSolver.cpp#L92

But I am not quite sure about that.

Best regards,
Sherlp
