Hi to all of you.
First, I would like to thank all of you for sharing your enriching experience with us.
I found a good and easy example of the Schwarz alternating method in the FreeFEM++ documentation (V4.6) for a linear elliptic problem. my goal is to find the maximum norm error estimate between the exact solution and the iterated Schwarz sequence. I adapted to my nonlinear elliptic PDE and it successfully worked.
Now, I am asking whether somebody has a ready example of the additive Schwarz method as I could not find anyone in the mentioned documentation. In fact, all it was mentioned was about the parallel usage of the software.
Your assistance is hugely appreciated.
