Running ABACUS with DeePKS model
Once the DeePKS training process is converged,
users may perform ABACUS SCF calculation with
the DeePKS model loaded. Compared to a normal
ABACUS SCF job with lcao basis, one needs to
add the following keywords to INPUT
file:
<...other keywords>
deepks_scf: 1 # run SCF job with DeePKS model
deepks_model: model.ptg # provide the model file; should be correctly located
Note that the path of model.ptg
should be
provided along with the file itself. The above
input works only if model.ptg
and INPUT
are placed under the same directory.
Users also need to provide the projector file
along with the path in STRU
:
<...other keywords>
