See https://github.com/FEniCS/dolfinx/issues/159.
An option to force convert 3D mesh to 2D mesh (by stripping last component away) would be very useful.
Some users are preparing planar (2D) meshe…

`GenericFunction` is too generic, covers too wide range of scenario.
This generality leads to implicit behaviour.
Example 1: Values of BCS are GenericFunction. Inside DirichletBC call to `Generic…

Is `using la_index_t = PetscInt;` needed now, when PETSc is required?

The PointSource command appears to be removed in DOLFIN-X. Is there any plan to put it back in?

Detected using valgrind:
```

Tests in `test.XDMF.py` are way too slow. Python loops over entities of non-trivial meshes are performed.

I'll continue my remove mood here.
I propose to remove `Constant` class as a part of dolfin. Let me explain:
`Constant` is used basically for 2 types of action:
1. In UFL expression (for assembly…

The file `python/dolfin/io.py` appends just some (read_checkpoint, ) methods of `HDF5File` and `XDMFFile` classes.
If user doesn't do `import dolfin.io` then `python/dolfin/io.py` is not run and me…

Consider the following
```
from dolfin import *
mesh = UnitSquareMesh(MPI.comm_world, 1, 1)
mesh.geometry.coord_mapping = fem.create_coordinate_map(mesh.ufl_domain())
V = FunctionSpace(mesh, …
