Python API usage

Quick start:

>>> import logging
>>> logging.basicConfig(level=logging.DEBUG)

>>> from fsm_eigenvalue.compute import parameter_sweep
>>> from fsm_eigenvalue.load import load_data_from
>>> from import store_results_to

>>> data_file = 'examples/data-files/barbero-viscoelastic.yaml'
>>> results_file = data_file.replace('.yaml', '.hdf5')

>>> beam_type_id, search_space, nodal_graph, strip_data, materials, astiff_shape = load_data_from(data_file)
>>> with parameter_sweep(beam_type_id, search_space, strip_data, materials, astiff_shape) as results_iterator:
...     store_results_to(results_file, data_file, search_space, astiff_shape, results_iterator)
