[deal.II] Re: On using project_boundary_values_div_conforming for (RT-DG) in parallel case

Hi Konrad, Thanks for your reminder. After upgrading to v9.1.1, everything goes well now. It seems an issue of the last version of dealii and has already been fixed: https://github.com/dealii/dealii/pull/7327 . Regards, Charlie On Wednesday, September 11, 2019 at 7:43:45 PM UTC+2, Konrad Simon

[deal.II] On using project_boundary_values_div_conforming for (RT-DG) in parallel case

Hi there, I'm trying to make step-20 parallel through trilinos (by following step-40/55), but haven't succeeded. In setup_system() function, I set owned_partitioning, relevant_partitioning and constraints in the following way: dof_handler.distribute_dofs (fe); DoFRenumbering::component_wise(d

[deal.II] On using block diagonal preconditioner for the mixed Poisson problem

Dear all, I'm trying to use a block-diagonal preconditioner for the mixed Poisson problem from step-20, but haven't made it yet. The diagonal preconditioner of interest is from Powell & Silvester,2003
