That depends on your specific problem and your personal preferences, so there is no easy answer to that question. Do you need to represent discontinuous solutions? Can you resolve these areas with your mesh? Then DG might give you an advantage. DG is often more expensive, though. -- Timo Heister http://www.math.tamu.edu/~heister/ _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
