Hi folks, I think this did not go through. If I am wrong, please excuse the double-posting.

I then use these two parameters in the invocation of create_triangulation, along with empty SubCellData. My problem is now that imposing Dirichlet boundary conditions goes wrong. Please excuse my ignorance as a new users of deal: I assumed that create_triangulation would determine the boundary faces itself. However, it doesn't seem to be the case and the boundary_indicator of the faces is not set the way it should be. Is there any way to perform this with built-in functions of deal or do I have to try the painful path of implementing an algorithm myself? Or is there an easier way to just assign fixed values to certain nodes (they don't seem to have this boundary_flag)? Thanks a lot for your assistance _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
