"""Visualizing unstructured element (Shell, Plane, Brick) Response.

Parameters
----------
odb_tag: Union[int, str], default: 1
Tag of output databases (ODB) to be visualized.
ele_tags: Union[int, list], default: None
The tags of elements to be visualized.
If None, all elements are selected.
slides: bool, default: False
Display the response for each step in the form of a slideshow.
Otherwise, show the step with the largest response.
ele_type: str, default: "Shell"
Element type, optional, one of ["Shell", "Plane", "Solid"].
resp_type: str, default: None
Response type, which dependents on the element type `ele_type`.
#. For ``Shell`` elements, one of ["sectionForces", "sectionDeformations"].
I.e., section forces and deformations at Gaussian integration points (per unit length).
If None, defaults to "sectionForces".
#. For ``Plane`` elements, one of ["stresses", "strains"].
I.e., stresses and strains at Gaussian integration points.
If None, defaults to "stresses".
#. For ``Brick`` or ``Solid`` elements, one of ["stresses", "strains"].
I.e., stresses and strains at Gaussian integration points.
If None, defaults to "stresses".
resp_dof: str, default: None
Dof to be visualized, which dependents on the element type `ele_type`.
.. Note::
The `resp_dof` here is consistent with stress-strain (force-deformation),
and whether it is stress or strain depends on the parameter `resp_type`.
#. For ``Shell`` elements, one of ["FXX", "FYY", "FXY", "MXX", "MYY", "MXY", "VXZ", "VYZ"].
If None, defaults to "MXX".
#. For ``Plane`` elements, one of ["sigma11", "sigma22", "sigma12", "p1", "p2", "sigma_vm", "tau_max"].
* "sigma11, sigma22, sigma12": Normal stress and shear stress (strain) in the x-y plane.
* "p1, p2": Principal stresses (strains).
* "sigma_vm": Von Mises stress.
* "tau_max": Maximum shear stress (strains).
* If None, defaults to "sigma_vm".
#. For ``Brick`` or ``Solid`` elements, one of ["sigma11", "sigma22", "sigma33", "sigma12", "sigma23", "sigma13", "p1", "p2", "p3", "sigma_vm", "tau_max", "sigma_oct", "tau_oct"]

* "tau_max": Maximum shear stress (strains).
* "sigma_oct": Octahedral normal stress (strains).
* "tau_oct": Octahedral shear stress (strains).
* If None, defaults to "sigma_vm".
style: str, default: surface
Visualization mesh style of surfaces and solids.
One of the following: style='surface' or style='wireframe'
Defaults to 'surface'. Note that 'wireframe' only shows a wireframe of the outer geometry.
show_values: bool, default: True
Whether to display the response value.
show_outline: bool, default: False
Whether to display the outline of the model.
