.. _auto_eigout_parser:

*EIGOUT PARSER*
===============

Parses an LS-DYNA eigout file from an uploaded file or a simulation and returns a dataset with one row per eigenvalue mode, including the eigenvalue, frequency (radians and Hz), period, and the modal effective masses (translation and rotation).
