Name error in Cosmosolvationparameter
« on: December 21, 2023, 14:25 »
Hello everyone,
I am trying to run the py file given in the tutorials for solvation energy in 2023 version [( https://docs.quantumatk.com/manual/Types/SolvationEnergy/SolvationEnergy.html#NL.Analysis.SolvationEnergy.SolvationEnergy ) and I am getting name error.  So What I do to solve the error?

 
# Set minimal log verbosity
setVerbosity(MinimalLog)

# Define elements
elements = [Nitrogen, Hydrogen, Hydrogen, Hydrogen]

# Define coordinates
cartesian_coordinates = [[ 0.            ,  0.            ,  0.            ],
                         [ 1.06999992324 ,  0.            ,  0.            ],
                         [-0.35666664108 ,  0.            , -1.008805602123],

    elements=elements,
    cartesian_coordinates=cartesian_coordinates

solvation_parameters = CosmoSolvationParameters(
    solvent_dielectric_constant=2.3741,
    solvent_surface_tension=27.9*dyne/cm
)

calculator = LCAOCalculator(
    basis_set=basis_set,
    solvation_parameters=solvation_parameters
)

# Set the calculator
configuration.setCalculator(calculator)
configuration.update()
nlsave('ammonia_toluene.hdf5', configuration)

# Optimize the geometry
optimized_configuration = OptimizeGeometry(
    configuration=configuration,
    trajectory_filename='ammonia_toluene.hdf5'
)
nlsave('ammonia_toluene.hdf5', optimized_configuration)

# Calculate the solvation energy
solvation_energy = SolvationEnergy(
    configuration=optimized_configuration
)
nlsave('ammonia_toluene.hdf5', solvation_energy)

From the log output it states that you are using version T-2022.03. The Cosmo solvation model was first introduced in the U-2022.12, see release notes: https://www.synopsys.com/content/dam/synopsys/silicon/quantum-atk/pdf/qatk-datasheet-u-2022-12-release-notes.pdf

So solution is to upgrade to a newer version.

Thank you. Now I have the solvation energy.
