ExcMessage("Found a set of normal vectors that are nearly collinear.")The error does not occur when a boundary condition of u=0 is used on the two flat boundaries, nor when I use my no_normal_flux boundary conditions on a hyper_cube. The error can be replicated by changing the domain and boundary conditions accordingly to the Step 32 (developer version). Any help in this matter would be greatly appreciated!
Can you come up with a small program that triggers this error? Take a look at the existing test cases for this function in
http://dealii.org/svn/dealii/trunk/tests/deal.II/no_flux_01.cc through http://dealii.org/svn/dealii/trunk/tests/deal.II/no_flux_09.cc to see how such a test should ideally look like.
