Dear all,
Convergence problem is kinda mysterious...
This time convergence is nor reached when the mesh is dense. I would say perhaps too dense in some region. Some coarser mesh leads to convergence. What's the possible reason for this?
From my point of view, the sub-domain with more elements has more weight in the quantity used to evaluate convergence. Then importance of sub-domain with too dense mesh may be overemphasized. The convergence becomes sensitive to the behavior there. So too dense mesh only in some part may not be a good idea. What do you think?
Gracias!
