Dear all I have problems involving airfoil geometry where the cells have high aspect ratio in the boundary layer. Due to this, it is not enough to just use curved boundaries but the interior faces also need to be curved. See the attached figure gridq1.pdf
I have implemented a method based on winslow equations, see http://persson.berkeley.edu/pub/fortunato15winslow.pdf http://dl.acm.org/citation.cfm?id=2884302 Using this winslow method, I can generate an euler vector that gives valid cells, see gridqk.pdf which uses degree=4. Using this euler vector, I want to create a MappingFEField and use that in my Navier-Stokes DG code. I have some doubts. When I use a MappingFEField, do I still need to attach manifold descriptions to the curved boundaries ? Assume that I am not doing any grid adaptation. If I want to adapt the grid, is there a way to use the MappingFEField to place the new points ? Are there any functions in deal.II to measure the quality of the mesh ? The Winslow eqn approach seems quite useful and one can write a general class that may be useful for many people. At present I only have a serial implementation. The approach is as follows: Start with a Q1 mesh Attach manifolds Solve the winslow eqn to get the euler vector Create a MappingFEField Thanks praveen -- 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.
