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=True, debug=False, log=None, debug_file=None, mode='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_geom : bool; default=False

reads the BDF tables

debug : bool; 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_file : default=None -> no debug

sets the filename that will be written to

mode : str; default=’msc’

{msc, nx}

export_hdf5_file(self, hdf5_file, exporter=None)

Converts the OP2 objects into hdf5 object

Parameters:

hdf5_file : H5File()

an h5py object

exporter : HDF5Exporter; default=None

unused

TODO: doesn’t support:

• BucklingEigenvalues

gpdt_to_nodes(self)

converts the GPDT & EQEXIN tables to node ids

is_geometry

read_op2(self, op2_filename=None, combine=True, build_dataframe=None, skip_undefined_matrices=False, encoding=None)

class pyNastran.op2.op2_geom.OP2GeomCommon(make_geom=True, debug=False, log=None, debug_file=None, mode=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

interface for the OP2Geom class for to loading subclasses

Initializes the OP2 object

Parameters:

make_geom : bool; default=False

reads the BDF tables

debug : bool; 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_file : default=None -> no debug

sets the filename that will be written to

mode : str; default=None -> ‘msc’

{msc, nx}

save(self, obj_filename='model.obj', unxref=True)

Saves a pickleable object

pyNastran.op2.op2_geom.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)

Creates the OP2 object without calling the OP2 class.

Parameters:

op2_filename : str (default=None -> popup)

the op2_filename

combine : bool; default=True

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

will be used for superelements regardless of the option

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

list of [subcase1_ID,subcase2_ID]

exclude_results / include_results : List[str] / str; default=None

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

validate : bool

runs various checks on the BDF (default=True)

xref : bool

should the bdf be cross referenced (default=True)

build_dataframe : bool; default=False

builds a pandas DataFrame for op2 objects

skip_undefined_matrices : bool; default=False

True : prevents matrix reading crashes

log : Log()

a logging object to write debug messages to

(.. seealso:: import logging)

debug : bool; default=False

enables the debug log and sets the debug in the logger

debug_file : str; default=None (No debug)

sets the filename that will be written to

encoding : str

the unicode encoding (default=None; system default)

Returns:

model : OP2()

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
