[deal.II] Newton's method: compute residual in Step 15 and 57

Hi all, I am confused with Newton's method's residual computation (i.e., L2 norm of the system residual vector) in Step-15 and Step-57. In Step-15, to eliminate the residual component corresponding to the Dirichlet boundary condition, DOFTools::extract_boundary_dofs() is used to explicitly

Hi everyone, I have one question when i using DoFHandler ::cell_iterator DataPostprocessorInputs::CommonInputs < spacedim

Re: [deal.II] How to use create_mass_matrix tools with FESystem

Hi, In the stacktrace it looks like the error does not come from create_mass_matrix but from VectorTools::project. It complains that the passed Function has 1 component when it should have dim components. If you are projecting your own function, you need to make sure you set the number of
