This is the pyNastran.op2.op2_geom.rst file.

op2_geom Module

Defines:

• read_op2_geom(op2_filename=None, combine=True, subcases=None,

  exclude_results=None, include_results=None, validate=True, xref=True, build_dataframe=False, skip_undefined_matrices=True, mode=’msc’, log=None, debug=True, debug_file=None, encoding=None)

• OP2Geom(make_geom=True, debug=False, log=None, debug_file=None, mode=’msc’) - OP2

class pyNastran.op2.op2_geom.OP2Geom(make_geom: bool = True, debug: bool = False, log: Optional[Any] = None, debug_file: Optional[str] = None, mode: str = 'msc')

Bases: pyNastran.bdf.bdf.BDF, pyNastran.op2.op2_geom.OP2GeomCommon

creates an interface for the OP2 and BDF classes

Initializes the OP2 object

Parameters

make_geombool; default=False

reads the BDF tables

debugbool; default=False

enables the debug log and sets the debug in the logger

log: log()

a logging object to write debug messages to (.. seealso:: import logging)

debug_filedefault=None -> no debug

sets the filename that will be written to

modestr; default=’msc’

{msc, nx}

export_hdf5_file(hdf5_file, exporter=None)

Converts the OP2 objects into hdf5 object

Parameters

hdf5_fileH5File()

an h5py object

exporterHDF5Exporter; default=None

unused

TODO: doesn’t support:

• BucklingEigenvalues

gpdt_to_nodes()

converts the GPDT & EQEXIN tables to node ids

property is_geometry

read_op2(op2_filename: Union[str, pathlib.PurePath, None] = None, combine: bool = True, build_dataframe=None, skip_undefined_matrices: bool = False, encoding: Optional[str] = None)

see OP2.read_op2

class pyNastran.op2.op2_geom.OP2GeomCommon(make_geom: bool = True, debug: bool = False, log: Optional[Any] = None, debug_file: Optional[str] = None, mode: Optional[str] = None)

Bases: pyNastran.op2.op2.OP2, pyNastran.op2.tables.geom.geom1.GEOM1, pyNastran.op2.tables.geom.geom2.GEOM2, pyNastran.op2.tables.geom.geom3.GEOM3, pyNastran.op2.tables.geom.geom4.GEOM4, pyNastran.op2.tables.geom.ept.EPT, pyNastran.op2.tables.geom.mpt.MPT, pyNastran.op2.tables.geom.edt.EDT, pyNastran.op2.tables.geom.edom.EDOM, pyNastran.op2.tables.geom.dit.DIT, pyNastran.op2.tables.geom.dynamics.DYNAMICS, pyNastran.op2.tables.geom.axic.AXIC

interface for the OP2Geom class for to loading subclasses

Initializes the OP2 object

Parameters

make_geombool; default=False

reads the BDF tables

debugbool; default=False

enables the debug log and sets the debug in the logger

log: log()

a logging object to write debug messages to (.. seealso:: import logging)

debug_filedefault=None -> no debug

sets the filename that will be written to

modestr; default=None -> ‘msc’

{msc, nx}

save(obj_filename: str = 'model.obj', unxref: bool = True) → None

Saves a pickleable object

pyNastran.op2.op2_geom.attach_op2_results_to_bdf(bdf_model: pyNastran.bdf.bdf.BDF, op2_model: Optional[pyNastran.op2.op2.OP2] = None, validate: bool = True) → pyNastran.op2.op2_geom.OP2Geom

We’re up-converting a BDF and an OP2 result into an OP2Geom object.

pyNastran.op2.op2_geom.bdf_to_op2_geom(model: pyNastran.bdf.bdf.BDF, validate: bool = True) → pyNastran.op2.op2_geom.OP2Geom

converts a BDF() -> OP2Geom()

pyNastran.op2.op2_geom.read_op2_geom(op2_filename: Optional[Union[str, PurePath]] = None, combine: bool = True, subcases: Optional[List[int]] = None, exclude_results: Optional[List[str]] = None, include_results: Optional[List[str]] = None, validate: bool = True, xref: bool = True, build_dataframe: bool = False, skip_undefined_matrices: bool = True, mode: str = 'msc', log: SimpleLogger = None, debug: bool = True, debug_file: Optional[str] = None, encoding: Optional[str] = None)

Creates the OP2 object without calling the OP2 class.

Parameters

op2_filenamestr (default=None -> popup)

the op2_filename

combinebool; default=True

True : objects are isubcase based False : objects are (isubcase, subtitle) based;

will be used for superelements regardless of the option

subcasesList[int, …] / int; default=None->all subcases

list of [subcase1_ID,subcase2_ID]

exclude_results / include_resultsList[str] / str; default=None

a list of result types to exclude/include one of these must be None

validatebool

runs various checks on the BDF (default=True)

xrefbool

should the bdf be cross referenced (default=True)

build_dataframebool; default=False

builds a pandas DataFrame for op2 objects

skip_undefined_matricesbool; default=False

True : prevents matrix reading crashes

logLog()

a logging object to write debug messages to

(.. seealso:: import logging)

debugbool; default=False

enables the debug log and sets the debug in the logger

debug_filestr; default=None (No debug)

sets the filename that will be written to

encodingstr

the unicode encoding (default=None; system default)

Returns

modelOP2()

an OP2 object

Todo

creates the OP2 object without all the read methods ..

.. note: this method will change in order to return an object that

does not have so many methods
