WorkChain to converge test on cohisive energy of input structure

classmethod define(cls, spec)

Define the specification of the process, including its inputs, outputs and known exit codes.

A metadata input namespace is defined, with optional ports that are not stored in the database.

extra_setup_for_rare_earth_element(self)

Extra setup for rare earth element

extra_setup_for_fluorine_element(self)

Extra setup for fluorine element

setup_code_parameters_from_protocol(self)

Input validation

_get_inputs(self, ecutwfc, ecutrho)

get inputs for the evaluation CohesiveWorkChain by provide ecutwfc and ecutrho, all other parameters are fixed for the following steps

run_reference(self)

run on reference calculation

run_samples(self)

run on all other evaluation sample points

get_result_metadata(self)

define a dict of which is the metadata of the results, e.g. the unit of the properties return a list type

for example:

return {

‘absolute_unit’: ‘eV/atom’, ‘relative_unit’: ‘%’,

}

helper_compare_result_extract_fun(self, sample_node, reference_node, **kwargs)

extract

results(self)

set results of sub-workflows to output ports
