I have installed Mathematica+Documentation (v13.2) on a MacBook Pro in order to explore what appear to be excellent example tutorials on acoustics. In particular, I wanted to experiment with the following built-in example:

PDEModels/tutorial/Acoustics/ModelCollection/RoomEigenfrequencies

I am able to load the notebook, and am able to evaluate some of the initial cells. When I evaluate the first cell, I get the following message:

Do you want to automatically evaluate all the initialization cells in the notebook "RoomEigenfrequencies.nb"?

I click Yes, but encounter an issue when I reach the following cell/code:

furnitureBmesh = Import[FileNameJoin[{
ParentDirectory[
NotebookDirectory[], 6], "SupportFiles", "furniture.stl"}], 
   "ElementMesh"];
furnitureMesh = ToElementMesh[furnitureBmesh];
RegionPlot3D[furnitureMesh, Sequence[
 PlotTheme -> "Detailed", PlotLegends -> None, 
  AxesLabel -> {"x", "y", "z"}, PlotStyle -> Directive[LightGray], 
  Mesh -> None, ImageSize -> Medium]]

Evaluating this cell results in the following error message:

Import::nffil: File /Library/Wolfram/Documentation/13.2/en-us/Documentation/SupportFiles/furniture.stl not found during Import.

The code above references contents of a directory "SupportFiles" which is specified as a relative path with respect to the tutorial notebook. Checking on my hard drive, the directory "SupportFiles" does not seem to exist (either at the specified relative path or anywhere else in Mathematica-related directories).

I do not know if this is an idiosyncrasy related to this specific tutorial file (which might contain stale references), or if I am missing the directory "SupportFiles" that should have been created when I installed Mathematica.

Any guidance on this question will be appreciated!
