Elastic Properties#
Calculate the bulk modulus for Aluminium using the GPAW DFT code:
Equation of State#
One way to calculate the bulk modulus is using the Equation of State to calculate the equilibrium properties:
from ase.build import bulk
from atomistics.calculators.ase import evaluate_with_ase
from atomistics.workflows import get_tasks_for_energy_volume_curve, analyse_results_for_energy_volume_curve
from gpaw import GPAW, PW
task_dict = get_tasks_for_energy_volume_curve(
structure=bulk("Al", a=4.05, cubic=True),
num_points=11,
vol_range=0.05,
axes=["x", "y", "z"],
)

In the first step the EnergyVolumeCurveWorkflow object is initialized including all the parameters to generate
the strained structures and afterwards fit the resulting energy volume curve. This allows the user to see all relevant
parameters at one place. After the initialization the function generate_structures() is called without any
additional parameters. This function returns the task dictionary task_dict which includes the tasks which should
be executed by the calculator. In this case the task is to calculate the energy calc_energy of the eleven generated
structures. Each structure is labeled by the ratio of compression or elongation. In the second step the task_dict
is evaluated with the GPAW simulation code using the evaluate_with_ase() function:
result_dict = evaluate_with_ase(
task_dict=task_dict, ase_calculator=GPAW(xc="PBE", mode=PW(300), kpts=(3, 3, 3))
)

In analogy to the task_dict which defines the tasks to be executed by the simulation code the result_dict summarizes
the results of the calculations. In this case the energies calculated for the specific strains. By ordering both the
task_dict and the result_dict with the same labels, the EnergyVolumeCurveWorkflow object is able to match the
calculation results to the corresponding structure. Finally, in the third step the analyse_structures() function takes
the result_dict as an input and fits the Equation of State with the fitting parameters defined in the first step:
fit_dict = analyse_results_for_energy_volume_curve(output_dict=result_dict, task_dict=task_dict)

The bulk modulus for Aluminium is calculated using the GPAW simulation code by fitting the Equation of State with a third order polynomial over a volume range of +/-5% to be 72.3GPa.
Elastic Matrix#
An alternative approach to calculate the bulk modulus is based on the relation B = (1/3) (C11 + 2 C12 ). The bulk
modulus can be calculated based on the sum of the first elastic constant C11 and twice the second elastic constant C12
divided by there.

In analogy to the example with the EnergyVolumeCurveWorkflow above, the ElasticMatrixWorkflow is initialized with all
the parameters required to generate the atomistic structures and afterwards fit the resulting energies. By calling the
generate_structures() function the task dictionary task_dict is generated. The task dictionary specifies that the
energy should be calculated for a total of thirteen structures with different displacements. In the second step the
structures are again evaluated with the GPAW simulation code:
result_dict = evaluate_with_ase(
task_dict=task_dict, ase_calculator=GPAW(xc="PBE", mode=PW(300), kpts=(3, 3, 3))
)

The atomistic structures are evaluated with the evaluate_with_ase() function, which returns the result_dict. This
result_dict in analogy to the task_dict contains the same keys as well as the energies calculated with the
GPAW simulation code. Finally, the result_dict is provided as an input to the
analyse_structures() function to calculate the corresponding elastic constants:
elastic_dict = analyse_results_for_elastic_matrix(output_dict=result_dict, sym_dict=sym_dict)

The bulk modulus calculated from the elastic constants C11 and C12 based on a strain of +/- 5% is calculated with
the GPAW simulation code to be 74.9GPa. This differs from the bulk modulus calculated
from the Equation of State above by 2.6GPa. In comparison to the experimental bulk modulus for Aluminium which is
reported to be 76GPa the calculation based on the elastic constants
seem to be more precise, still this is more likely related to error cancellation. In general elastic properties calculated
from density functional theory are expected to have errors of about 5-10% unless carefully converged.
