`export_mcids` Module

Defines:

nodes, bars = export_mcids(bdf_filename, csv_filename=None)

pyNastran.bdf.mesh_utils.export_mcids.export_element_cid(bdf_filename: BDF | str, eids: list[int] | None = None, log=None, debug=False)[source]

Exports the element coordinates systems for non-isotropic materials.

Note that for two quads identically oriented/numbered PSHELL quads with theta different between the two, the element cid will be same.

pyNastran.bdf.mesh_utils.export_mcids.export_mcids(bdf_filename: BDF | str, csv_filename: str | None = None, eids: list[int] | None = None, export_xaxis: bool = True, export_yaxis: bool = True, consider_property_rotation: bool = True, iply: int = 0, log=None, debug=False)[source]

Exports the element material coordinates systems for non-isotropic materials.

Parameters:

bdf_filenamestr/BDF

a bdf filename or BDF model

csv_filenamestr; default=None

str : the path to the output csv None : don’t write a CSV

eidslist[int]

the element ids to consider

export_xaxisbool; default=True

export the x-axis

export_yaxisbool; default=True

export the x-axis

consider_property_rotationbool; default=True

rotate the coordinate system

iplyint; default=0

TODO: not validated the ply to consider

pid_to_npliesdict[int pid, int nplies]; default=None -> auto

optional dictionary to speed up analysis

PSHELL

Returns:

nodes(nnodes, 3) float list: the nodes
bars(nbars, 2) int list: the “bars” that represent the x/y axes of the coordinate systems
