Sorry, if my question(and english language) is not clear enough. Yes those "triangles" mesh are what I call "disordered mesh". By design, my mesh generator produces only quadrangular elements(with area nearly 1e-10), but after few refinments in deal.ii paraview shows those pictures: one refinment, two. three times and one with bigger view on mesh)
