Dear Christof,

Hello, this is Seongyeol Kim of Ulsan National Institute of Science and Technology.

I am currently using the OPAL code for the beamline simulation.

Normally, I use ASTRA for the linac section simulation, and using the output file from the ASTRA,

I converted it for the OPAL format (injected) and I used it as an input for the OPAL transfer line simulation.

During the simulation, I always face the error 'ParallelTTracker > * Deleted ~ particles, remaining 9031 particles'
I would like to know how to fix this problem. This error occurs from 10 mm propagation (even before entering a single element).

I guess the problem is on the particle distribution, so I checked and flipped the longitudinal distribution

(for the head // tail convention), but still there is the error messgae.

Could you please let me know how to solve this issue? Please find attached input files for the issue I have.

Thank you for your consideration and help in advance!

Best regards,

Seongyeol
