The tests show I have the simple ones down correctly. My only worry is slice. I think I might be picking a convention that is not what we assume when...

I am trying to apply periodic boundary conditions on my computational domain. I have a system with one variable defined in the whole domain and another variable defined in a...

The 2D and 3D shape computations are massive switch statements on the element type and the order. In that form it likely does not make sense to inline them for...

Using std::optional to avoid breaking API. This is needed in moose element subdomain modifier where we need to project a function onto a subset of the mesh.

Currently dof number ordering for higher order variables on the same dof object are like this: `var_0_comp_0 var_0_comp_1 var_0_comp_2 var_1_comp_0 var_1_comp_1 var_1_comp_2` This is inefficient if you want to treat...

For @YaqiWang and just better overall "moral correctness" (credit to @roystgnr)

Currently we rely on the global `libMesh::n_threads()` but we want to be able to set thread counts differently for different MOOSE applications running in MultiApp contexts. Proposed by @GiudGiud

User can control the percentage of smoothness values above which p-refinement is favored in hp-adaptivity. For instance, default value is set as 0.9, means p refining favored on an element...

Hello everyone, I have a D-shaped domain and I generated infinite elements on the circular boundary of my domain. I issued a mesh.find_neighbors(); after generating as shown in the examples....

Just an idea. If when we have non-conformality we could just decide the element that is faced with a node in the middle of its face is a poly, then...
