Hi Everyone,
Now I have an inverse problem that is given the measured displacement u_i
and our target to get the force field f_j. If I unstand correctly that the
linear system of dealii is A_{ij}u_j = f_i. I am not sure this form
whether I can use the L2 regularization argmin{||u-u_{measure}|| +
\lamda||f|| }. I have only had experience with A_(ij)f_j = u_i. Then we
have an analytical solution using SVD. However, If we have A_{ij}u_j =
f_i, it looks like we do not have analytical solution.
Does anyone have any ideas on how to solve this inverse problem using
dealii?
Best regards,
Yunfei
