pyyeti.nastran.bulk.wttabdmp1

pyyeti.nastran.bulk.wttabdmp1(f, setid, freq, damp, damping_type='crit')[source]

Write a Nastran TABDMP1 card to a file.

Parameters:

  • fobj (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.

  • setid (integer) – The tabid ID number.

  • freq (1d array_like) – The frequencies, in Hertz, at which the damping is defined.

  • damp (1d array_like) – The damping value at each frequency. This array must have the same length as freq.

  • damping_type (string; optional) – The type of damping. Must be one of ‘g’, ‘crit’, or ‘q’. If not specified, it defaults to ‘crit’.

Notes

This card will be written in 16 fixed-field format using the wtcard16() function.

The freq and damp parameters must have a length of at least 2.

Examples

>>> from pyyeti import nastran
>>> setid = 101
>>> freq = [0.1, 2.5, 3.0]
>>> damp = [0.01, 0.015, 0.015]
>>> nastran.wttabdmp1(1, setid, freq, damp)
