Using the module Semiconductors for computing electric potential in a certain geometry, sometimes during convergence process one can observe how few cells of the mesh close to both exterior limits and contacts (ohmic or Schottky), assume values clearly far from the expected. These sets of cells constitute a sort of splodges which prevent convergence uselessly. How to eliminate them? Can I interrupt the convergence progress and manage the individual cell values in those cases when I am completely sure of more appropriate ones?
