Crystal into amorphous

GROMACS version: 2018
GROMACS modification: Yes/No
Dear Justin,
Is it possible to work on the melting temperature of different phases of a substance with GROMACS? Is it possible to convert a crystal into amorphous with GROMACS?
Best regards

Sure, if the force field you’re using is sufficiently accurate as to model the phase transition. That’s the limitation, not the software.
