### Describe new/missing feature
It is known that the Poisson equation has infinite solutions when the boundary conditions like pure neuman are considered. In the Legacy DOLFIN, we use the Lagrange M…

Consider the following:
```
from mpi4py import MPI
from dolfinx import *
import ufl
mesh = UnitSquareMesh(MPI.COMM_WORLD, 1, 1)
V = FunctionSpace(mesh, ufl.FiniteElement("CG", mesh.ufl_cell(…

Hi @srosenbu
I just noticed that something like
```python
q = fem.Function(Q) # Q is the scalar quadrature space
q.interpolate(lambda x: x[0], cells=cells)
```
will fill the entries according…

Due to a compiler bug the latest rollout of MSVC on GitHub cannot build nanobind (and hence Basix or DOLFINx Python wrappers). MS has a fix internally, when it is rolled backout re-enable the Windows …

Greetings to everyone!
I found a bug in the periodic boundary condition. The error occurs only in the parallel case.
Here is a simple test case on which an error occurs https://gist.github.com/A…

Hi Mark, thank you so much for your great idea to extent the FEniCS package to solve high dimensional PDE. As you know, FEniCS are now updated to FEniCSx and dolfin to dolfinx, and the old version is …

I think that the documentation below is not enough for a user to be able to use the function and the examples…

### Describe new/missing feature
Currently, we only support mesh refinement on triangular and tetrahedral meshes.
We should aim to support:
- 1D (non-uniform) refinement of intervals
- 2D (uniform…
