segmentation fault (core dumped)

Dear Steve and Friends,
I am a new to Lammps. I am trying to simulate graphene and octane system. I ask my system to compute the temperature and the pressure of octanes in the flow and I am getting the error of segmentation fault (core dumped) . I enclosed my Lammps Script and many thanks in advance for your help and time.
Best regards,
suu

a segmentation fault is a very unspecific error message and can have
many causes including hardware issues.
with certain MPI libraries, you will get a segfault under all
circumstances, where you have an input error. so check your output
more carefully.

enclosed my Lammps Script and many thanks in advance for your help and time.

please clean up your input and remove all commands that are commented
out and also remove those not required to cause the segfault.
at the very least you should *always* report which version of LAMMPS
you are using and on what platform you are running.
also try with as small a system as possible. that way you can also
provide the data file to the mailing list and people can actually try
to reproduce it.
with the limited information you provide, it is impossible to give any
meaningful advice.
