Quantum chemistry program executor and IO standardizer (QCSchema) for quantum chemistry.
A simple example of QCEngine's capabilities is as follows:
>>> import qcengine as qcng
>>> import qcelemental as qcel
>>> mol = qcel.models.Molecule.from_data("""
O 0.0 0.000 -0.129
H 0.0 -1.494 1.027
H 0.0 1.494 1.027
""")
>>> inp = qcel.models.AtomicInput(
molecule=mol,
driver="energy",
model={"method": "SCF", "basis": "sto-3g"},
keywords={"scf_type": "df"}
)These input specifications can be executed with the compute function along with a program specifier:
>>> ret = qcng.compute(inp, "psi4")The results contain a complete record of the computation:
>>> ret.return_result
-74.45994963230625
>>> ret.properties.scf_dipole_moment
[0.0, 0.0, 0.6635967188869244]
>>> ret.provenance.cpu
