why does using the Partial Differential Equation (PDE) Toolbox, I get the following error: PDEModel does not have a mesh?

model = createpde('thermal');
geo = multicylinder([20,25,35],20,'Void',[1,0,0]);
model.Geometry = geo;
pdeplot(model, 'FaceLabels', 'on')
generateMesh(model);
pdemesh(model)


thermalProperties(model,"Cell",1,"ThermalConductivity",40);
thermalProperties(model,"Cell",2,"ThermalConductivity",0.05);
thermalBC(model,"Face",3,'Temperature',80);
thermalBC(model,"Face",7,'Temperature',4);

result = solve(model);
pdeplot3D(model,'ColorMapData',result.Temperature)

Please use pdegplot, if you want to plot geometry.

pdegplot(model,'FaceLabels','on')
