pyvista.examples.downloads.download_aero_bracket#

download_aero_bracket(load=True)[source]#

Download the finite element solution of an aero bracket.

Data generated from public SimScale examples at SimScale Project Library - Turbo.

Licensing for this dataset is granted to freely and without restriction reproduce, distribute, publish according to the SimScale Terms and Conditions.

This project demonstrates the static stress analysis of three aircraft engine bearing bracket models considering both linear and nonlinear material definition. The models are tested with horizontal and vertical loading conditions as provided on the GrabCAD - Airplane Bearing Bracket Challenge.

Parameters:

loadbool, default: True: Load the dataset after downloading it when True. Set this to False and only the filename will be returned.

Returns:

pyvista.UnstructuredGrid | str: DataSet or filename depending on load.
