Yes the plate is clamped on the left side and the fluid domain extends further through the front and back of our view so I guess that the only DM zone needed is the one I already have (system coupling set for the plate). Still, I don't get why it is not remeshing.
Furthermore I was thinking about the size of the cells; as you can see in 1st or 2nd screenshot there are some cells really small and with very stretched shape. Can they be a problem if the displacement become remarkable and for some reason Fluent is forcing a smoothing instead of remeshing? Is it possible that they degenerate?Â
