Did you check out "man core"? Did you look in journalctl

I don't know if or when they fixed it, but at some point
systemd also squashed core files in /etc/systemd/system.conf
by changing DefaultLimitCORE. They made it impossible
for a user to run "ulimit -c unlimited". I had to set:
DefaultLimitCORE=0:infinity
to make it possible to change my ulimit in a user session.
My complete set of changes I now make to my system to restore
traditional core file behavior is:
systemctl list-unit-files | fgrep abrt
Then do a
systemctl mask whatever.service
for all the "whatever"s that fgrep found
edit /etc/sysctl.conf add as last line
kernel.core_pattern = core
edit /etc/systemd/system.conf and set
DefaultLimitCORE=0:infinity
reboot system and you should now get "normal" core files.
