pyyeti.nastran.bulk.rdseconct

pyyeti.nastran.bulk.rdseconct(f, *, follow_includes=True, include_symbols=None, encoding='utf_8')[source]

Read Nastran SECONCT cards from a Nastran bulk file.

Parameters:

  • f (string or file_like or None) – Either a name of a file, or is a file_like object as returned by open(). If file_like object, it is rewound first. Can also be the name of a directory or None; in these cases, a GUI is opened for file selection.

  • follow_includes (bool; optional) – If True, INCLUDE statements will be followed recursively. Note that if f is a StringIO object, or another object that does not have a name property, this parameter will be set to False.

  • include_symbols (dict; optional) – A dictionary mapping Nastran symbols to an associated path. These can be read from a file using rdsymbols().

  • encoding (string; optional) – Encoding to use when opening text file. This option will be passed to any files read in via the follow_includes option.

Returns:

a_ids, b_ids (1d ndarrays) – Array of GRID and SPOINT ids for superelement A and superelement B, respectively. Both outputs will be empty if no SECONCT cards found.

Notes

This routine uses rdcards() to load the data.

Examples

>>> from io import StringIO
>>> from pyyeti import nastran
>>> bulkdata = (
...     "SECONCT,101,0,,NO\n"
...     ",3,30,11,110,19,190,27,270\n"
...     "$\n"
...     "SECONCT,101,0,,NO\n"
...     ",1101,THRU,1104,2101,THRU,2104\n"
... )
>>> with StringIO(bulkdata) as f:
...     a_ids, b_ids = nastran.rdseconct(f)
>>> a_ids
array([   3,   11,   19,   27, 1101, 1102, 1103, 1104]...)
>>> b_ids
array([  30,  110,  190,  270, 2101, 2102, 2103, 2104]...)
