PDE Model Boundary Conditions

Hi Everyone,
I have a question regarding the Matlab PDE Model Boundary Conditions.
Currently, I am working with a 2D mesh with heatflux on one egdes. This egdes has 9 nodes. When I looked at state.u I recognized that this is a 1x12 array. But why?

If you output state.x and state.y in the function, you can see to which evaluation points state.u belongs.

If you use a heatflux condition, the temperatures at the boundary are not known in advance. I'm not sure how the PDE Toolbox approximates the temperatures in the node points. Maybe with some helper points to approximate dT/dn in the node points ?
But if you need this information reliably, you should contact MATLAB support.
