## Reason
My motivation is for solving variational inequality problems, but as @fdkong points out grid sequencing can be generally useful for solving highly nonlinear problems. For VI problems, as no…

Hi! I am trying to implement 2 pdes, solving one at a time. From the first one I obtain a variable that I need to include in the second one.
The implementation of the first and second equations are:

Hello,
It would be great if we could get an implementation of scipy.linalg.solve_banded in jax.
Otherwise I am interested in similar methods for solving matrix equations of the form `A*x=b` where …

Hi, I am interested in solving systems of 2D PDEs with single and mixed derivative terms. I started by adding a single mixed derivative term to the [Gray-Scott example](http://www.chebfun.org/examples…

The Navier-Stokes equations, which describe the motion of fluid substances such as liquids and gases, are fundamental to the field of fluid dynamics. However, several challenging problems related to t…

The following code:
```
A = sprand(3000,3000,0.2);
x0 = rand(3000,1);
F = @(x) diag(x.^2)*A*x;
J_ad = AutoDiffJacobian(F, x0);
```
does not work. Error message is:

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…

Hi!
I'm the lead developer over at [MethodOfLines.jl](https://github.com/SciML/MethodOfLines.jl), and it's come time for me to implement flux limiters for use when solving Hyperbolic PDEs. In try…

Hi,
how do you usually initialize the frequency of the network (leaving aside the magic number 30)?
As it is very much problem-dependent, I'm wondering if it is currently just a trial-and-error ta…

Hi, I'm a big fan of `DGL` and always use it for my GNN projects.
I wonder what will be a friendly DGL practice for handling dynamic (?) graphs.
It might be good to start with my own definition of…
