Hi,
When I try to import my STL file into MATLAB I get en error message. What am I doing wrong?
figure
gm = importGeometry('Torus.stl');
pdegplot(gm)
Error: Check for missing argument or incorrect argument data type in call to function 'importGeometry'.

If you want to create a geometry using some edge coordinates, then hit this help:
doc geometryFromEdges % Explains via a good simple example: Geometry from Decomposed Solid Geometry

You are missing one important part in your command, see e.g.:
pdem = createpde(); % Missing
GM = importGeometry(pdem,'BEAM.stl'); % See how to add the missing piece
pdegplot(gm, 'FaceLabels','on', 'FaceAlpha',0.75)

How can I use geometryFromEdges now and continue?
So basically I want to import a 3D CAD Object (a simple plate) and then use geometryFromEdges() to perform thermal analysis.
thermalmodel = createpde('thermal','transient');
gm = importGeometry(thermalmodel,'BEAM.stl');
geometryFromEdges(thermalmodel,????); % What am I supposed to add here
