Hello all,
I am using Be and C system in which diamond is cutting beryllium for which potentials have been defined. Tersoff for diamond and eam pot. for Beryllium amd morse pot. between Be and C. But the error occurs.
Following is interatomic potentials code written in MD program:

pair_style hybrid tersoff eam/allloy morse 1.75
pair_coeff * * tersoff SiC.abop.tersoff NULL NULL NULL C C C
pair_coeff * * eam/alloy BeAgrawal.eam.alloy Be Be Be NULL NULL NULL
pair_coeff 1*3 4*6 morse 2.566 1.7798 1.666

ERROR on proc 0:
Failed to allocate 2066932500 bytes for array neigh:binhead <../memory.cpp:64>

​this error message has **nothing** to do with the potentials.



Kindly suggest the solutions.
