I noticed that we can calculate the Poisson ratio of a crystalline metals with LAMMPS. I wonder if we can use that example for a metallic glass! If no, is there any other way, with another software?

$\begingroup$ @CodyAldaz thanks for attention. One can find the file of "in.elastic" in directory like it in their computer "...\LAMMPS 64-bit 22Aug2018-MPI\Examples\ELASTIC\in.elastic". In the first line of the file of "in.elastic", it is written, "Compute elastic constant tensor for a crystal". Moreover, in the 7th line of the same file, it is written "must be modified for different crystal structures". According to these, it seems that this file can just calculate the Poisson ratio of the crystalline material. $\endgroup$– user1099Commented Jul 21, 2020 at 21:43

As far as I know, and read here, metallic glasses akin to crystalline metals are isotropic. To this end, if we use the script provided in the examples of LAMMPS, to what extent we can secure the results that we want, i.e Poisson Ratio, Young's modulus, etc.
