add_node(id, x, y, z, additional_card_data="")¶

Parameters

idint: id of the node
xfloat: x-coordinate
yfloat: y-coordinate
zfloat: z-coordinate
additional_card_datastr: further card data (see Notes section).

Returns

nodeNode: newly created part object

Raises

ValueError: if id does already exist in the database

Notes

The additional_card_data is a string appended to the keyword when writing the output file. The string is appended behind the coordinates.

Examples

>>> # (optional) TC and RC fields for node
>>> additional_data = "       0       0"
>>> node = kw.add_node(123, 3.141, 5.926, 5.35, additional_data)

get_nNodes()¶

Returns

nNodesint: number of nodes in keyword

Examples

>>> kw.get_nNodes()
26357

get_node_ids()¶

Returns

node_idslist of int: isd of all nodes in the card

Examples

>>> kw.get_node_ids()
[1, 2, 3, 4]

get_nodes()¶

Returns

nodeslist of Node: all node objects in the keyword

Examples

>>> len(kw.get_nodes())
26357

load()¶

Raises

RuntimeError: if a parsing error occurs

Notes

This function parses the string data in the node object. The function is automatically triggered when reading an input file.

One may also assign new node data as a string to the keyword and trigger load manually.

The string data will be erased during parsing and thus is removed from the string buffer.

Examples

>>> # The keyword has already one node
>>> kw.get_nNodes()
1
>>> # lets see it
>>> print(kw)
*NODE
$ some comment line
$     id               x               y               z
       1              0.              0.              0.
>>> # append new node data to the keyword
>>> kw.append("       2              0.              0.              0.")
>>> # and load it
>>> kw.load()
