When I get the `FaceGeometricFactors` for 2-D boundaries in 3-D space, the Jacobian matrix is empty. The code is
```
if (dim == 2)
const FaceGeometricFactors *face_geom = mesh->GetFaceGeometricF…

**Describe the bug 🐞**
The new NonlinearSolve v3.15 (with DI in it) causes a BoundaryValueDiffEq solve to error or segfault.
**Expected behavior**
The solve should run without errors, as it …

With 9 months of experience behind us, IMO `--ignore fmap-jacobian` should always be used if the fieldmap is not PEPolar, but it is critical for at least some PEPolar cases.
I think we should disab…

Hi,
I’m trying to use the CAT12 toolbox to compute DBM maps from T1w images. I used the default parameters and saved the Jacobian determinant map. The resulting map seems to have an issue in which …

Can we get any example when we have an array of functions, rather than a single one. This is quite a common case, when we need to compute Jacobian. I think I have some idea how to do that, but I am no…

Hi Anthony,
Do you have the derivation steps of this jacobian matrix or any material/links for better understanding?
Thanks a lot !

HI! I was looking at the example in the docs about how to perform [nested AD with Lux](https://lux.csail.mit.edu/stable/manual/nested_autodiff) with Lux. The code in the documentation definitively wor…

Dear Firedrakers,
It seems that `'snes_type':'test'` as mentioned in the docs (https://www.firedrakeproject.org/solving-interface.html#checking-the-provided-jacobian) is no longer supported by PE…

Hi,
I write a for loop to loop over many random parameter sets, for each parameter set it will produce 20 daughter parameter sets by small value mutation of each parameter, then I will plot the bif…
