pyyeti.nastran.bulk.wttload1

pyyeti.nastran.bulk.wttload1(f, setid, excite_id, delay, excite_type, tabledi_id)[source]

Write a Nastran TLOAD1 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 load set ID number

  • excite_id (integer) – The ID of the load set definition (LOAD, SPCD, etc cards).

  • delay (integer or float) – The time delay. If this is a float, it represents the delay in seconds. If it is an integer, it references a DELAY card.

  • excite_type (string) – The type of excitation. Must be one of ‘load’, ‘disp’, ‘velo’, or ‘acce’.

  • tabledi_id (integer) – The ID of a TABLEDi card that defines the transient.

Notes

This card will be written in 8 fixed-field format using the wtcard8() function.

This card is useful to add a load set to the P matrix when creating an external superelement using EXTSEOUT. In that case, the referenced TABLEDi card does not need to exist.

Examples

>>> from pyyeti import nastran
>>> setid, excite_id = 201, 202
>>> delay = .05
>>> excite_type = "load"
>>> tabledi_id = 1501
>>> nastran.wttload1(1, setid, excite_id, delay, excite_type, tabledi_id)
