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…

There is a lot of new finite difference functions (not one liners) required for the adjoint TTI. You can see it in the new notebook. Do you think we want to keep the s…

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…

Dear BOUT++ community
I am studying the transport model, where the expression of the model can be found at https://iopscience.iop.org/article/10.1088/1741-4326/ad2d39 (i.e., equation 1, 6, 10, A5, …

There's a lot of nuance behind how one decides to discretize in z. For example, in the microlens array example, the structure is sliced such that the upper corner of each slice lies right on the ideal…

Compact finite difference schemes are families of high-order implicit operators for derivatives on structured rectilinear or curvilinear grids, most commonly used for hyperbolic PDEs for their favorab…

Creating an issue to document. A new finite-difference Maxwell solver with no dispersion along one axis is proposed in a [recent paper](https://arxiv.org/abs/1906.10500). Its properties are somewhat s…

I am wondering: is there a good way for us to define operators that make it easy to implement WENO and Cheng-Cooper discretizations? @ranocha do you have ideas on this? Here's a starter of the kind of…
