write_mesh_files Module

This file defines:

• WriteMesh

class pyNastran.bdf.bdf_interface.write_mesh_file.WriteMeshs

Bases: pyNastran.bdf.bdf_interface.write_mesh.WriteMesh

Defines methods for writing cards

Major methods:

• model.write_bdf(…)

• model.echo_bdf(…)

• model.auto_reject_bdf(…)

creates methods for writing cards

_write_aero_control_file(bdf_files: Any, size: int = 8, is_double: bool = False, is_long_ids: Optional[bool] = None) → None

Writes the aero control surface cards

_write_aero_file(bdf_files: Any, size: int = 8, is_double: bool = False, is_long_ids: Optional[bool] = None) → None

Writes the aero cards

_write_bdf_includes(out_filenames, bdf_files, relative_dirname=None, is_windows=True)

Writes the INCLUDE files

Parameters

out_filenamesdict[fname]fname2

fname_in - the nominal bdf that was read fname_out - the bdf that will be written

relative_dirnamestr; default=None -> os.curdir

A relative path to reference INCLUDEs. ‘’ : relative to the main bdf None : use the current directory path : absolute path

is_windowsbool; default=None

True/FalseWindows has a special format for writing INCLUDE

files, so the format for a BDF that will run on Linux and Windows is different.

None : Check the platform
