# Model Card for Model ID |
|
|
|
|
|
This repository contains the FlashMD universal models. These are models designed to run accelerated molecular dynamics for chemical systems across the periodic table. |
|
|
|
|
|
## Model Details |
|
|
|
|
|
These models offer acceleration with respect to traditional molecular dynamics by allowing the use of larger steps. Each FlashMD model follows the following naming |
|
|
convention: `flashmd_{mlip}_{timestep}fs.ckpt`, where "mlip" is the name of the MLIP (machine-learned interatomic potential) that was used to generate the training |
|
|
trajectories for the FlashMD model, and {timestep} is the FlashMD timestep in fs. The corresponding MLIP is also made available as `mlip_{mlip}.ckpt`. |
|
|
|
|
|
At the moment, we have: |
|
|
|
|
|
- mlip = "pet-omatpes" (with timestep={1,2,4,8,16,32,64,128}): these are FlashMD models trained on the PET-OMATPES MLIP, and therefore allowing to run FlashMD at the |
|
|
r2SCAN level of theory |
|
|
- earlier models used in the reference paper ("flashmd_{timestep}fs.pt", with timestep={1,4,8,16,32,64}), only supported by `flashmd<=0.1.2` and useful to reproduce |
|
|
older results. These are trained on the PET-MAD MLIP and therefore reproduce molecular dynamics at the PBEsol level of theory |

|
|
|
|
These models are supposed to be used with the flashmd package, which is available on PyPI (`pip install flashmd`). |
