Now I encounter a more complicated case. What if the stiffness tensor is not constant, but a function of eta, as shown in PDF "non-constant elastic tensor.pdf". Is it possible to implement it based on the modified code "Ronghai.py"?

That's fine, thanks. I have modified your file and it runs. Note that you still need to specify some boundary conditions so that the matrix is not singular.
