get_field for CBEAM

[clarkbr...@gmail.com]

Steve,

I'm still trying to figure out how stuff works. Here is an FYI. Doesn't seem right to me, but..

model.Element(3001)
Out[100]:
$inboard right upper spar 0 caps for wing
CBEAM       3001    3001    3007    3034     -1.      0.      0.

Walking through the fields:

model.Element(3001).get_field(1)
Out[105]: 3001

model.Element(3001).get_field(2)
Out[106]: 3001

model.Element(3001).get_field(3)
Out[107]: 3013

model.Element(3001).get_field(4)
Out[108]: 3034

Unit 5,6, & 7 balk like

model.Element(3001).get_field(5)
Traceback (most recent call last):

  File "C:\ProgramData\Anaconda3\lib\site-packages\pyNastran\bdf\cards\base_card.py", line 196, in get_field
    key_name = self._field_map[n]

KeyError: 5

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

  File "<ipython-input-109-d896041b9213>", line 1, in <module>
    model.Element(3001).get_field(5)

  File "C:\ProgramData\Anaconda3\lib\site-packages\pyNastran\bdf\cards\base_card.py", line 199, in get_field
    value = self._get_field_helper(n)

  File "C:\ProgramData\Anaconda3\lib\site-packages\pyNastran\bdf\cards\base_card.py", line 170, in _get_field_helper
    raise IndexError(msg)

IndexError: CBEAM has not overwritten _get_field_helper; out of range

Turns out this is the x vector trio and the x parm/attr will get it

model.Element(3001).x
Out[111]: array([-1.,  0.,  0.])

Clark,

It looks the get_field method isn't supported for the CBEAM.

Personally, I use the g0/x method.  It's really meant for something general like OpenMDAO.
