Re: time-step of integer size 1 not allowed
Hello Tiago,
I have not tried this and will do so, thank you kindly for your advice.
Best,
Julianne

Dear Julianne,
The problem seems to be caused by the time-stepping not being sufficient for the required configuration. Have you tried to activate the ENLARGE_DYNAMIC_RANGE_IN_TIME directive?
Kind regards,

Hello all,
I am running a cosmological zoom simulation with a 50Mpc periodic box including gas and dark matter from z=99 with about 70 million total particles. I have included the details of the latest version of this run from the log at the end of this email. I have tried several different configurations and settings within the code and with the cluster I am running on (number of nodes/processors), however I keep encountering the same error at some redshift between z=30 and z=9 depending on the configuration:
"Code termination on task=1, function timebins_get_bin_and_do_validity_checks(), file src/time_integration/timestep.cc, line 508: time-step of integer size 1 not allowed"
I have not been able to identify the source of this error, any guidance or help would be greatly appreciated.
Thank you,
Julianne
