model = createpde;
TR = stlread('AneursymModel-2.stl');
importGeometry(model,'AneurysmModel-2.stl');

Now used the stlread but the Error i am getting

Error using stlread (line 40)

Unable to open file 'AneursymModel-2.stl'.

Hi Sasikala,

The "Unable to open file" error is most often caused by the following reasons:

Incorrect path specified: Double-check that the file path you provided is correct and points to the location of the STL file. Instead of providing a relative file path, try specifying the full file path to the STL file. For example, use something like “C:\path\to\your\file.stl” on Windows or “/path/to/your/file.stl” on macOS/Linux.
Incorrect permissions: Ensure that you have the necessary permissions to access the file. If the STL file is located in a restricted directory, you may need to adjust the file permissions or move the file to a location accessible by MATLAB.

You can run

exist('AneursymModel-2.stl','file')

for checking if the file is in the current working directory or on MATLAB path searched by MATLAB.

Hope this helps!
