get_nodal_responses

opstool.post.get_nodal_responses(odb_tag, resp_type=None, node_tags=None, print_info=True)[source]

Read nodal responses data from a file.

Return type:

Dataset

Parameters

odb_tag: Union[int, str], default: one

Tag of output databases (ODB) to be read.

resp_type: str, default: None

Type of response to be read. Optional:

  • “disp” - Displacement at the node.

  • “vel” - Velocity at the node.

  • “accel” - Acceleration at the node.

  • “reaction” - Reaction forces at the node.

  • “reactionIncInertia” - Reaction forces including inertial effects.

  • “rayleighForces” - Forces resulting from Rayleigh damping.

  • “pressure” - Pressure applied to the node.

  • If None, return all responses.

Note

If the nodes include fluid pressure dof, such as those used for …UP elements, the pore pressure should be extracted using resp_type="vel", and the value is placed in the degree of freedom RZ.

node_tags: Union[list, tuple, int], default: None

Node tags to be read. Such as [1, 2, 3] or numpy.array([1, 2, 3]) or 1. If None, return all nodal responses.

Note

If some nodes are deleted during the analysis, their response data will be filled with numpy.nan.

print_info: bool, default: True

Whether to print information

Returns

NodalResp: xarray.Dataset

Nodal responses’ data.

Note

The returned data can be viewed using “.data_vars,” .dims, .coords, and .attrs to view the dimension names and coordinates. You can further index or process the data.
