[deal.II] Re: Periodic boundary conditions seem to be not applied

Hi Bastien, Which version of deal.II are you using? There is the recently added add_periodicity() function that helps join otherwise unrelated faces for distribut

[deal.II] Re: Doubt in FEvalues

Dear Rajat, Thanks for posting an example along the lines of your implementation. Well, from the output you've shown there, I'm not surprised that there's some problem. If I'd thrown in some asserts then it would have been more clear, but the two volume calculations "Using GridTools" and "Calcu

[deal.II] Computational domain evolving with time, how to achieve this in dealii?

Hi, all: I am doing a free surface problem, and I want to get the computational domain evolving with time. Since after every time step, the domain boundary needs to be updated, so I need to redefine a new trianglation for the next time step according to my solution at previous time step. But I

[deal.II] Periodic boundary conditions seem to be not applied

Hi, I am working on a 2D square, a incompressible neo-hookean material. I've used step 44 and modified it to work on a two field formulation (*u* and p). I am trying to implement periodic boundary conditions for the vertical displacement on lateral faces (right and left). My left face has bounda

[deal.II] Re: Doubt in FEvalues

Hello Jean, First of all, thanks a lot for taking time to write to me and explaining this issue. I am also very keen on solving this issue. I looked at the code you sent and indeed it looks like what you say is correct. However, If I calculate the gradients, it is giving wrong results and gi

[deal.II] Re: Doubt in FEvalues

Hi Rajat, Without your code, its difficult to say what's going wrong here. It should (and does) work as I've explained. In summary, FEValues gets to know about any changes you've made to the underlying because its reinit() call takes an *active* cell which always knows its geometry (you manipul

[deal.II] Re: Doubt in FEvalues

Hello Jean, Thanks for your reply. In my case, since I am physically moving the mesh ( as I was discussing here ), even after calling fe_values.reinit(cell), I am getting the gradients on the geometry before mesh movement which shoul
