Re: [deal.II] Creating a FESystem with bulk and surface FE spaces

HI Manuel, I’ve got a brief answer to your followup questions, but let me first say that Andrew’s suggestion, which seems to be the most elegant/optimal approach to the problem, is one that is possible to for you to realise. It’s also made me think that perhaps some of the tools that have been

Re: [deal.II] Creating a FESystem with bulk and surface FE spaces

Hi Andrew, This definitely helps! Although I still have to check the code in detail, I found and scanned through your paper a few days ago (before posting my question here). I went to the link in the paper to find and look at the code, but the link is broken so I decided to ask for help here.

Re: [deal.II] Creating a FESystem with bulk and surface FE spaces

Hi Manuel, I’m not sure if this helps, but some time ago we developed a code for surface elasticity in deal.ii. In this problem the surface of a bulk has its own energetic structure. One effectively constructs system matrices for volume cells and surface cells and these contribute to the same

Re: [deal.II] Creating a FESystem with bulk and surface FE spaces

Hi Jean-Paul, I have taken a look at FE_Nothing and hp::DoFHandler. If I understand correctly, the idea is that all the interior cells will use an FE_Nothing space and the boundary cells will use a standard FE_Q space, right? My question is what happens to the DoFs that are shared by a cell

Re: [deal.II] Creating a FESystem with bulk and surface FE spaces

Hi Manuel, As a small addition to what Wolfgang has already suggested, you can also considering using the hp framwwork in conjunction with FE_Nothing elements in order to, effectively, disable elements in the interior of the

Re: [deal.II] Creating a FESystem with bulk and surface FE spaces

Manuel, I need to solve a system of many PDEs (currently 18). The actual number changes since the PDEs are defined by a truncated infinite sum and some recursive equations. Anyway, the first two equations are defined on a 2D or 3D domain (call it Omega) and the rest is only defined on the
