G4Exception : PART122 errror

How can I solve this error?

*** G4Exception : PART122
issued by : G4ParticleTable::Insert()
The particle Cs133 has already been registered in the Particle Table
*** Fatal Exception *** core dump ***

Waiting for suggestions

Hey

I see this is an old request, but I run into the same issue, when I include nuclear fragmentation during a carbon beam simulation

*** G4Exception : PART122
issued by : G4ParticleTable::Insert()
The particle F18 has already been registered in the Particle Table

I already tried a lot - rebuilding, avoid multithreaded, different seeds, etc. but with increased particle numbers I always run into this error. My colleagues experience the same error.

If there was a solution ti this problem, I would be very happy to know it!

Thanks a lot in advance!

This is a 3 years old thread and it ight be no longer relevant…

A fix for a similar issue affecting latest macOS/clang compiler is included in the latest patch release 11.4.3. You may want to try it out!

Cheers, Gabriele

Thank you so much for the reply! I will try that!

Best, Celine
