pyyeti.nastran.bulk.wttabled1

pyyeti.nastran.bulk.wttabled1(f, tid, t, d, title=None, form='{:16.9E}{:16.9E}', tablestr='TABLED1')[source]

Writes a Nastran TABLED1 (or similar) card to a file.

Parameters:

  • f (string or file_like or 1 or None) – Either a name of a file, or is a file_like object as returned by open() or io.StringIO. Input as integer 1 to write to stdout. Can also be the name of a directory or None; in these cases, a GUI is opened for file selection.

  • tid (integer) – ID for TABLED1 card

  • t (1d array_like) – time vector

  • d (1d array_like) – data vector

  • title (string or None; optional) – If a string, it is written as a comment before table. If None, no string is written.

  • form (string; optional) – String specifying the format of a single [time, data] pair. Expected to result in a string either 16 or 32 characters long.

  • tablestr (string; optional) – Name of card to write; must be same format as TABLED1.

Returns:

None

Notes

In the format string, include a # sign to force a decimal point to appear without trailing digits. For example, ‘{:8.2f}{:#8.0f}’ would print like this: ‘ 12.34 123456.’.
