You are mistaken. The quadrature points on the face of the tet will
not coincide with the nodes of the tet unless you are us

I am having trouble writing a modified version of the assembly function of
Introduction Ex 4. Example 4 demonstrates the method to solve the Poisson
equation.
My domain consists of a 3D unstructured mesh with tetrahedral elements. I
