Hej, thanks for your prompt answer!
Yes, your interpretation of my poor description is correct. So then I just
need to create a new FEValues within the cell loop containing the points where
I want to evaluate the shape functions, right? How do I add this points?
Also if the points are in the physical quad, do I need to map them to the
reference quad [-1,1]x[-1,1] before adding them, or I just add the points
directly to the FEValues?
Yes.
I think you probably want to read through the implementation of the
VectorTools::point_value() function, which does exactly what you want.
