After looking through the code, it appears that calculating the IJK coordinates for a face is part of the process for computing a cell boundary, and functions exist internally to convert these coordin…

I would like to save the solution vector on a subdivision mesh to vtk files. However, I noticed that the solution on all boundary nodes is set to zero, regardless of their previous values. This leads …

For multi-material simulations, interface discontinuities are needed.
Let $c$ be the concentration of hydrogen, we have
$$
\nabla \cdot ( D \nabla c) = -f \quad \text{on} \ \Omega
$$
and
$$

A logical region defined by subtraction of two regions is nether open nor closed. This leads to inconsistency in the overall design. The same region could be defined as a box or as a logical subtracti…

I noticed, while working on #6665, that the Eulerian mappings generate strange
pictures when combined with manifolds. Here is an example:

## Purpose
For global runs, we currently set up a spherical shell domain (extruded FD) and create fields that are defined everywhere on the domain. The issues arise in three areas:
- Interpolation: …

I am successfully using `MatrixFree::cell_loop()` with `FE_Nothing` and I wanted to use `MatrixFree::loop()` to impose Neumann boundary condition but that does not work. Is it something that we suppor…

We should facilitate construction of meshes like this:
namely matrix / spherical-inclusion type, where the inclusion might have different properties.
To that end we need to combine a variant…
