Does DPLR support simulation of different temperatures in one box?

[Ding-Hairui]

Hello, DPers.
I am planning to simulate the solid-liquid boundary of Fe with external electric field. According to my knowledge, the 'fix efield' and 'compute temp/region' commands in LAMMPS are related to this situation, and DPLR is more suitable for electric field. My questions are:

1. I've heard that some commands of LAMMPS are designed for specific potentials. Does DPLR support them?
2. If available, should the training data include solid-liquid boundary? Or dost DP just need data of solid and liquid structures?
   Thanks for your reply!

You may modify the fix dplr command as

fix		0 all dplr model ener.pb type_associate 1 3 bond_type 1 efield XX YY ZZ

To apply an external field of (XX, YY, ZZ) to the DPLR system. More details on DPLR is referred to the doc

The training data should sample all relevant configurations in applications.
