fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Kai Zhao

Dear Vladimir,

I use "compute cna/atom" in lammps, which should be a method of analyzing local structure.

Hi Vladimir,

Firstly, warm thanks for your answer. Indeed, these pictures are generated by OVITO. My question in nature is what is the difference of stacking fault and twin in MD snapshots. To the best of my knowledge, I've not found any books or papers that can clearly describe the difference of atomic structure between these two kinds of defect.

Thanks very much for these papers, they are useful for me!
