export_mcids Module

Defines:

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

pyNastran.bdf.mesh_utils.export_mcids._add_elements(nid, eid, nodes, bars, centroid, iaxis, jaxis, export_both_axes, export_xaxis)

adds the element data

pyNastran.bdf.mesh_utils.export_mcids._export_coord_axes(nodes, bars, csv_filename)

save the coordinate systems in a csv file

pyNastran.bdf.mesh_utils.export_mcids._export_quad(elem, nodes, iply, nid, eid, pids_failed, bars, export_both_axes, export_xaxis, consider_property_rotation)

pyNastran.bdf.mesh_utils.export_mcids._export_tria(elem, nodes, iply, nid, eid, pids_failed, bars, export_both_axes, export_xaxis, consider_property_rotation)

helper method for export_mcids

pyNastran.bdf.mesh_utils.export_mcids._get_elements(model, eids)

pyNastran.bdf.mesh_utils.export_mcids._rotate_mcid(elem, pid_ref, iply, imat, jmat, normal, consider_property_rotation=True)

rotates a material coordinate system

pyNastran.bdf.mesh_utils.export_mcids.export_mcids(bdf_filename, csv_filename=None, eids=None, export_xaxis=True, export_yaxis=True, iply=0, log=None, debug=False)

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

Parameters:

bdf_filename : str/BDF

a bdf filename or BDF model

csv_filename : str; default=None

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

eids : List[int]

the element ids to consider

export_xaxis : bool; default=True

export the x-axis

export_yaxis : bool; default=True

export the x-axis

iply : int; default=0

TODO: not validated the ply to consider

PSHELL

iply location —- ——–

0 mid1 or mid2 1 mid1 2 mid2 3 mid3 4 mid4

PCOMP/PCOMPG

iply location —- ——– 0 layer1 1 layer2

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
