Re: [deal.II] Help with step-7 Neumann boundary conditions

Dear Wolfgang, Thanks for a quick reply, and sorry for ambiguity. To be more precise (trying to be) I should say the lines I modified with the aim of creating a so-called "view" do not do that for my intended variable. My question mainly was that if using the [ ] operator (that I added) does the j

[deal.II] Help with step-7 Neumann boundary conditions

Hi everyone, I am trying to mimic step-7 implementation of Neumann boundary condition in the case of a vector-valued problem. I did some modifications as shown in the below, but it doesn't work as expected; const FEValuesExtractors::Scalar pressure(0); . cell_rhs(i) += (

Re: [deal.II] FunctionManifold class

Giuseppe, Searching for FunctionMnaifold in the tests folder should give you a couple of examples on how to use FunctionManifold with an analytical function. Most of them use std::strings but tests/fe/fe_values_function_manifold.cc and tests/mappings/mapping_q_manifold_02.cc actually use Function
