**Describe the current issue**
The `CheckpointFile` doesn't retain any information on mesh hierarchies, so if you generate a mesh hiearchy you can't save it to a file and load it up later to use with…

**Describe the bug**
When solving using a list of boundary conditions, changing their order in the list results in divergence.
**Steps to Reproduce**
Minimal example:
```python
import firedrake…

Running the following code in parallel
```py
from firedrake import *
mesh = PeriodicIntervalMesh(3, 1)
mh = MeshHierarchy(mesh, 3)
```
raises the exception

**Describe the bug**
An invalid type conversion error ocurs when we try to rescale a VectorFunction by pre-multiplying by a single entry of a `numpy.array`.
**Steps to Reproduce**

When trying to create a `LinearVariationalProblem` from the derivative of a form, UFL throws an error if:
- The mesh is a manifold
- The coordinate degree is greater than 1
- The form includes th…

When I try to use geometric multigrid with vinewtonrsls I get the error below. It only pops up with rsls (not ssls) and is raised just by setting the option (not yet specifying the bounds).

Hi,
I am using a python environment named Firedrake (PDE solver) together with another libraries called pygmsh to implement a dynamical system inside the function **f(x,u)**. When I try to run the…

Currently, our `forward` and `backward` methods require calls to `assemble`. This requires banging on Firedrake's cache of compiled forms each time to see if the form has already been compiled... Th…

e.g. for SciPy's L-BFGS-B using a (non $l^2$) Riesz map will lead to the derivative being supplied to the optimizer being inconsistent. SciPy requires the (non-mapped) derivative.
