Good evening!
I'm working on the Discontinuous Galerkin solver based on MFEM. When I've profiled the code by gperftools, I saw that I should compute values of shape functions every time step severa…

Restart files _require_ a Discontinuous Galerkin (DG) version of the dyn grid data (meaning that the corresponding edge dofs on bordering elements need to be separately saved), while right now, our IO…

Good day!
I am currently learning how to use MFEM in order to solve problems through Discontinous Galerkin approach, and I am finding myself stuck when trying to add boundary conditions to my probl…

Hello :)
I would like to use the Discontinuous Petrov-Galerkin (DPG) method, explained in Example 8, to solve `Div.(1/A*Grad(p)) = 0`.
My main problem at the moment is the boundary conditions, …

For the use of HDG (Hybridizable Discontinuous Galerkin) in Hou10ni software, we may provide internal edges (in 2D) or faces (in 3D). However triangle/tetgen outputs from MMG do not provide this inte…

I hope I get that right, but you are using the diffuse interface method solely to represent a solid interface, right? In that case, I suggest that you differentiate strongly from the diffuse interface…
