[求助] lammps计算程序警告提示求助

计算一个体系分解的时候出现以下警告和错误,请各位帮忙分析分析~~
把时间步长改小之后,没有错误了,但是依然有警告。
WARNING: OMP_NUM_THREADS environment is not set. (../comm.cpp:100)
  using 1 OpenMP thread(s) per MPI task
Reading data file ...
  orthogonal box = (0 0 0) to (26.9394 23.1102 22.0272)
  1 by 1 by 1 MPI processor grid
  1344 atoms

Warning: inconsistent vdWaals-parameters
Force field parameters for element SI
indicate  shielding without inner wall, but earlier
atoms indicate different vdWaals-method.
This may cause division-by-zero errors.
Keeping vdWaals-setting for earlier atoms.

atoms indicate different vdWaals-method.
This may cause division-by-zero errors.

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode -14.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
