class opstool.vis.FiberSecVis(ele_tag, sec_tag, results_dir='opstool_output', line_width=0.75, line_color='k', colormap='viridis', opacity=0.75)

A class to vis the fiber section in OpenSeesPy.

Parameters

ele_tag: int

The element tag to which the section is to be displayed.

sec_tag: int

Which integration point section is displayed, tag from 1 from segment i to j.

results_dir: str, default=”opstool_output”

The dir that results saved.

line_width: float, default = 0.75

The line width of mesh edges.

line_color: str, default = “k”

The color of mesh edges.

colormap: str, default = “jet”

Color map used to display the response.

opacity: float, default=0.75

Transparency of mesh.

Returns

FiberSecVis instance.

animation(output_file, input_file='FiberRespStepData-1.hdf5', show_variable='strain', show_mats=None, framerate=24)

fiber section response animation.

Parameters

output_file: str

The output file name, must end with .gif.

input_file: str, default=’FiberRespStepData-1.hdf5’

The file name that fiber section responses saved.

show_variable: str, default=’strain

Response type to display, optional “stress” or “strain”.

show_mats: Union[int, list[int], tuple[int]], default=None

Mat tag to dispaly. If None, all tags will display.

framerate: int, default=24

The number of frames per second.

Returns

None

resp_vis(input_file='FiberRespStepData-1.hdf5', step=None, show_variable='strain', show_mats=None)

fiber section response vis.

Parameters

input_file: str, default=’FiberRespStepData-1.hdf5’

The file name that fiber section responses saved.

step: int, default = None

Analysis step to display. If None, the step that max response; If -1, the final step; Else, the other step.

show_variable: str, default = ‘srain’

Response type to display, optional “stress” or “strain”.

show_mats: Union[int, list[int], tuple[int]]

matTags to dispaly. matTag is the material tag defined in openseespy, bu it must in the section. If None, all tags will display.

Returns

None

sec_vis(input_file='FiberData.hdf5', mat_color=None)

plot the fiber section.

Parameters

input_file: str, default=’FiberData.hdf5’

The file name that fiber section data saved.

Warning

Be careful not to include any path, only filename, the file will be saved to the directory results_dir.

mat_color: dict

Dict for assign color by matTag, {matTag1:color1,matTag2:color2, and so on} matTag is the material tag defined in openseespy, bu it must in the section.

Returns

None
