Node¶

Class for nodal data.

class qd.cae.dyna.Node¶

Container for handling nodal data.

Examples

Get nodes by

>>> femfile = D3plot("path/to/d3plot")
>>> node_list = femfile.get_nodes()
>>> node = femfile.get_nodeByID(1)
>>> node = femfile.get_nodeByIndex(1)

Methods

`get_accel`()	Get the time series of the acceleration vector.
`get_coords`()	Get the geometric nodal coordinates.
`get_disp`()	Get the time series of the displacement vector.
`get_elements`()	Get the elements of the node.
`get_id`()	Get the id of the node.
`get_vel`()	Get the time series of the velocity vector.

get_accel()¶

Get the time series of the acceleration vector.

Returns

dispnp.ndarray: time series of acceleration

Examples

>>> node.get_accel().shape
(34L, 3L)

get_coords()¶

Get the geometric nodal coordinates. One has to load the displacements for getting the coordinates at all timesteps.

Returns

coordsnp.ndarray: coordinate vector (nTimesteps x 3)

Examples

>>> d3plot = D3plot("path/to/d3plot")
>>> node.get_coords().shape
(1L, 3L)
>>> # load disp
>>> d3plot.read_states("disp")
>>> node.get_coords().shape
(34L, 3L)

get_disp()¶

Get the time series of the displacement vector.

Returns

dispnp.ndarray: time series of displacements

Examples

>>> node.get_disp().shape
(34L, 3L)

get_elements()¶

Get the elements of the node.

Returns

elementslist(Element): elements of the node

Examples

>>> len( node.get_elements() )
4

get_id()¶

Get the id of the node.

Returns

idint: id of the node

Examples

>>> d3plot.get_nodeByID(1).get_id()
1

get_vel()¶

Get the time series of the velocity vector.

Returns

dispnp.ndarray: time series of displacements

Examples

>>> node.get_disp().shape
(34L, 3L)
