Re: [deal.II] VectorTools::compute_nonzero_normal_flux_constraints on inner boundary and rientrant corners

2021-10-06 Thread Wolfgang Bangerth
I ran a test with a circular hole and a square hole. In both case I didn't get what I expected  (see images attached). Eventually, I need to solve the problem on an irregular inner boundary so I am looking for a robust method. I copied below the code. I very much appreciate any help with t

Upon closer inspection, one can see that the bottom left corner looks a bit "shaky" on the first 2 figures. This is an artifact of plotting. What you are trying to visualize is a bilinear function on the bottom left cell, but Paraview/Visit actually show is a subdivision of the square cell

Thank you for your reply Dr. Bangerth. I want to check which vertices are associated with the what DoFs. How can I extract them for each individual vertex? I could not find any relevant extract_<..>_dofs function to do it. Best, Raghunandan. On Tuesday, October 5, 2021 at 10:06:02 PM UTC-5 Wolf

[deal.II] Signature of TARGET_LINK_LIBRARIES in deal.II macros

2021-10-06 Thread 'David Schneider' via deal.II User Group
Hello everyone, I recently started a project with different dependencies and I'm running into an issue due to a CMake deal.II macro. I'm forced to use 'DEAL_II_SETUP_TARGET' as well as a similar macro from the other project and the projects use different versions of CMake's TARGET_LINK_LIBRARIE
