Nothing stops you from using different quadrature rules with different FEValues objects simultaneously. One pair with centroid will be auxiliary and not participate in integration directly (so you won’t use the weight associated to your single point quadrature rule anywhere). Whereas for integration on your linear elements you would most likely be using QGauss<dim> quarature(degree+1); Regards, Denis. -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
