Extractors
Compare changes
"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
.tsv (tab-separated values) file when fossils is used,.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',

]The values are calculated at the classical extractor list:
