Hi (Apologies, this is a resend**) ,
The ReaxFF potential is reported to reproduce stable graphite, diamond and carbon nanotube structures and even the formation of carbon-nanotube-like species*. I'm seeing different results when I compare AI-REBO and ReaxFF calculations for a (10,0) carbon nanotube. The configuration is stable for AI-REBO but explodes under ReaxFF. My question is: Is there something wrong with my input script or configuration file?
My files can be downloaded at this link http://www.njolee.net/LAMMPS/ReaxFF-AI-REBO_test.zip. It contains the following files:
"in.script.txt" - Input script contains commented/un-commented Reax/AI-REBO sections
"1PristineCNT(ReaxFF | AI-REBO)" - Configuration files for Reax/AI-REBO
"out.script.txt(ReaxFF | AI-REBO)" - Output files from Reax/AI-REBO runs
Reax/AI-REBO potential files
Thanks for you help!

**The UM Email Virus filter removed ReaxFF_AI_REBO test.zip__out.script.txt_AI_REBO because it
was found to be infected with the FILE FILTER= *.scr* virus or contains a prohibited file type.
All my files are text files, in ASCII format. I think the filenames containing the string "script" set off a false alarm.
