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

Note

The responses at all Gaussian points are averaged.

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 following step parameter.

step: Union[int, str], default: “absMax”

If slides = False, this parameter will be used as the step to plot. If str, Optional: [absMax, absMin, Max, Min]. If int, this step will be demonstrated (counting from 0).

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.

  1. For Shell elements, one of [“sectionForces”, “sectionDeformations”, “sectionForcesAtNodes”, “sectionDeformationsAtNodes”, “Stresses”, “Strains”, “StressesAtNodes”, “StrainsAtNodes”].

    If it endswith AtNodes, responses at nodes will be displayed, else responses at Gaussian integration points will be averaged for each element (per unit length). If None, defaults to “sectionForces”.

  2. For Plane elements, one of [“stresses”, “strains”, “stressesAtNodes”, “strainsAtNodes”].

    If it endswith AtNodes, responses at nodes will be displayed, else responses at Gaussian integration points will be averaged for each element. If None, defaults to “stresses”.

  3. For Brick or Solid elements, one of [“stresses”, “strains”, “stressesAtNodes”, “strainsAtNodes”].

    If it endswith AtNodes, responses at nodes will be displayed, else responses at Gaussian integration points will be averaged for each element. 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.

Important

The resp_dof parameter depends on the argument nd_material_type in opstool.post.CreateODB. It can only be one of the returned responses.

  1. For Shell elements

    • If resp_type is the section responses, one of [“FXX”, “FYY”, “FXY”, “MXX”, “MYY”, “MXY”, “VXZ”, “VYZ”].

    • “tau_max”: Maximum shear stress, 0.5*(p1-p3).

    • If None, defaults to “sigma11”.

shell_fiber_loc: Optional[Union[str, int]], default: “top”, added in v1.0.16

The location of the fiber point for shell elements. If str, one of [“top”, “bottom”, “middle”]. If int, the index of the fiber point to be visualized, from 1 (bottom) to N (top). The fiber point is the fiber layer in the shell section. Note that this parameter is only valid for stresses and strains in shell elements.

unit_symbol: str, default: None

Unit symbol to be displayed in the plot. This feature is added since v1.0.15.

unit_factor: float, default: None

This feature is added since v1.0.15. The multiplier used to convert units. For example, if you want to visualize stress and the current data unit is kPa, you can set unit_symbol="kPa" and unit_factor=1.0. If you want to visualize in MPa, you can set unit_symbol="MPa" and unit_factor=0.001.

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: False

Whether to display the response value by hover. Set to False can improve the performance of the visualization.

show_outline: bool, default: False

Whether to display the outline of the model.

show_defo: bool, default: False

Whether to display the deformed shape.

defo_scale: float, default: 1.0

Scales the size of the deformation presentation when show_defo is True. If set to False, the deformed shape will not be scaled (original deformation). If set to True or “auto”, the deformed shape will be scaled by the default scale (i.e., 1/20 of the maximum model dimensions). If set to a float or int, it will scale the deformed shape by that factor.

show_bc: bool, default: False

Whether to display boundary supports. Set to False can improve the performance of the visualization.

bc_scale: float, default: 1.0

Scale the size of boundary support display.

show_mp_constraint: bool, default: False

Whether to show multipoint (MP) constraint. Set to False can improve the performance of the visualization.

show_model: bool, default: False

Whether to plot the all model or not. Set to False can improve the performance of the visualization.

show_max_min: bool, default: False

Whether to show the maximum and minimum response values in the plot.

lazy_load: bool, default: False

Whether to lazily load the response data. If True, the response data will be loaded on demand when needed for plotting. This can save memory when dealing with large datasets. If False, all response data will be loaded into memory at once. If you encounter memory issues, consider setting this parameter to True, elsewise, set it to False for plotting in safety.
