I want to require the value of a shape function at some quadrature point. But
the following code throws an error saying finite_element_output is protected.
double shape_value = fe_values.finite_element_output.shape_values(i, q_index);
You already solved the problem, but just for completeness: You get the error
because you try to access a 'protected' member variable called 'shape_values'
(plural). What you want is to use the 'public' member function 'shape_value'
(singular).
