Lammps crashes in Window7 OS

Dear All,

I encountered a problem with Lammps when applying MEAM potential to Si. The Lammps is the latest version for 32-bit Windows.

My detailed situation is that: I wanted to calculate the ISF energy of Si on the glide planes and compare the results by using Tersoff and MEAM potentials. The MEAM library file is library.meam in Lammps’ package and the MEAM parameter file is obtained from Baskes’ paper [Phys. Rev. B 46 (1992) 2727–2742].

The lmp_mpi.exe (as well as lmp_serial.exe) run very well with Tersoff potential, but stoped working with MEAM. The system gave warnings as following:

问题事件名称: APPCRASH

(Unfortunately, my OS language is not English. True sorry for any inconvenience.)

I also attached the input scripts and MEAM library and parameter files. Does anyone encounter similar problems with me? Since the problem has troubled me for a long time, I would be most grateful if anyone like to help me to test my input scripts and check out what is the problem.

Thanks in advance.

Best regards,

Si.meam (57 Bytes)

your problem is know under the acronym GIGO.

your si.meam file is incorrectly formatted and the meam library code
does not (yet) do any sanity checks but simply crashes (or corrupts
memory and produces wrong results).

please check out other meam files in the potentials directory to see
the correct format.


also allowing only 10 minimization steps while expecting a *very*
tight convergence is ridiculous.
