pyyeti.nastran.bulk.rdtabled1

pyyeti.nastran.bulk.rdtabled1(f, name='tabled1', *, follow_includes=True, include_symbols=None, encoding='utf_8')[source]

Read Nastran TABLED1 or other identically formatted 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.

  • name (string; optional) – Name of cards to read.

  • 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:

dct (dictionary) – Dictionary of TABLED1 (or similar) cards:

{ID1: [time, data],
 ID2: [time, data], ...}

Notes

This routine uses rdcards() to load the data (can read 8 or 16 fixed field or comma-delimited).

Examples

>>> from pyyeti import nastran
>>> import numpy as np
>>> from io import StringIO
>>> t = np.arange(0, 1, .05)
>>> d = np.sin(2*np.pi*3*t)
>>> with StringIO() as f:
...     nastran.wttabled1(f, 4000, t, d, '3 Hz Sine Wave',
...                       form='{:8.2f}{:8.5f}')
...     dct = nastran.rdtabled1(f)
>>> np.allclose(t, dct[4000][:, 0])
True
>>> np.allclose(d, dct[4000][:, 1])
True
