the stop condition on the normalization run needs to be better analyzed. Specifically, we should understand where to position the monitor point. Before, it was in a far field point, outside the simulation cell. I've seen the simulation does not converge, at first glance. Now I'll try position it in a real physical point inside the cell. Let's see if it converges in a different way.
