I bet you need this at the quadrature points, and there the place to look is the FEValues class. It has a member normal() that does what you need when you use it via an FEValues (rather than FEFaceValues) object: https://www.dealii.org/current/doxygen/deal.II/classFEValuesBase.html#ac25ec6835799c3b6c7c842f8acb05eb3 Best W. -- ------------------------------------------------------------------------ Wolfgang Bangerth email: [email protected] www: http://www.math.colostate.edu/~bangerth/ -- 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.
