## Description
DVGeometryVSP parallel finite diff derivatives should have zero error compared to doing the same finite differences in serial. However, due to a bug in VSP, some processor's VSP models…

@jscuds @vsavram I didn't make this clear in #1, but there are 2 places in the LUNA algo where it will be useful to experiment with numerical methods: 1) The overall optimization algo, the focus of #…

This is more of a conceptual idea and not a real proposal yet.
**Is your feature request related to a problem? Please describe.**
`minimize` has convoluted logic of working with finite differenc…

I'm testing a simple 3D optimization setup, shown in the image below, consisting of a source plane, a design layer, and a monitor plane whose objective function is simply the flux of one polarization.…

Hi,
Recently, I have tried to use the package(""gsem","grmsem"), but i met a problem, can you please help me solve this?
Thank you very much!!
**Here is my code:**

As discussed in #894, the default step size of `1e-7` in the finite-difference method produces extremely large values for the gradient when run on a noisy device in tape mode.
A simple solution is …

Hello,
I was wondering whether there was documentation that illustrates how were derived the finite difference schemes that appear in the code?
In particular I am interested in the derivation o…

It will be in the ice flow *part*.
It will need to introduce finite difference.
Then solve the SIA equation with finite difference.
Then do some experiments with the model.
(Note that …

It is currently not possible to specify the finite differencing operators used by a calculation at runtime. At the moment, one can use Mathematica to generate multiple copies of a calculation, each w…
