DIY molecular dynamics for Xenes on crystal surfaces; where can I get applicable open-source force field parameters that I can use in my scripts?

The linked question(s) below describes a DIY project to simulate how Xenes (honeycomb nets of atoms like graphehe) behave on single crystal surfaces. Behaviors include rotation, strain, and heigh ...

Transiesta convergence issue

I have a graphene system (94 atoms - defective graphene) I was able to converge both right and left electrode runs in just 8 iterations. But the scattering run (transiesta) is not converging even ...
