Dear all I have included below an example code which converges with
commit ed1bdc6fc1931a664bc30920f66f054907a49cce but fails to converge with commit d1e3ffcaf6733e7d8509d93785b1f9e2b16a977e In this code, I solve the Winslow equations using continuous finite elements. I am using curved boundaries and I could reproduce the failure only with a complicated manifold. The manifold I use is a NACA0012 airfoil for which I have implemented a *project_to_manifold* function, see *winslow/parallel/naca.h*. I project the candidate point onto the true boundary in the normal direction to the boundary edge. The code is here https://bitbucket.org/cpraveen/deal_ii/src/master/winslow/parallel/?at=master To get the code git clone https://cprav...@bitbucket.org/cpraveen/deal_ii.git The code is in deal_ii/winslow/parallel Steps to run the code cd deal_ii/winslow/parallel cmake . make cd ../run gmsh -2 naca_struct.geo ../parallel/main 3 I realise that this is a bit complicated example but I dont know what to remove to simplify it. Any tips will be useful.
