save_eigen_data

opstool.post.save_eigen_data(odb_tag=1, mode_tag=1, solver='-genBandArpack', interpolate_beam=True)

Save modal analysis data.

Parameters

odb_tag: Union[str, int], default = 1

Output database tag, the data will be saved in EigenData-{odb_tag}.nc.

mode_tagint, optional,

Modal tag, all modal data smaller than this modal tag will be saved, by default 1

interpolate_beambool, optional,

Whether to interpolate beam eigenvectors for better visualization, by default True If True, the eigenvectors of beam elements will be interpolated by shape functions, i.e., more points will be generated along the beam elements.

solverstr, optional,

OpenSees’ eigenvalue analysis solver, by default “-genBandArpack”. See eigen Command
