Extractors

"Extractors" have been added to the model. They allow the user to read particular results such as the equivalent Von-Mises stress at given positions in the mesh after the FE analysis. The values are displayed in the console at the end of the calculation (if only 1 node is concerned). They are also saved to disc

• in a .tsv (tab-separated values) file when fossils is used,
• or in a .ascii file when Metafor is used.

The input syntax is documented [here in the wiki].(https://gitlab.uliege.be/rboman/fossils/-/wikis/input-file-for-boneload-simulations#extractors).

Some extractors have been added to models/dolicorhynchops/dolicorhynchops_10k.py:

    p['extractors'] = [
        {
            'name': 'tooth1',
            'nodes': [-10.20362, -17.46838, -229.9061],
            'variables': [ 'sigvm' ]
        },
        {
            'name': 'tooth2',
            'nodes': [-11.92466, 26.3042, -229.5354],
            'variables': [ 'sigxx', 'sigyy', 'sigzz', 'sigvm' ]
        },
        {
            'name': 'Lmuscle',
            'nodes': f'{path}/Lmuscle.stl',
            'variables': [ 'x0', 'y0', 'z0', 'sigvm' ]
        }
    ]

The values are calculated at the classical extractor list:
