I wanted to find a library that was fast for neighbourhood search and supported periodic boundary conditions and stumbled across this library. I gave it a quick try and I found it really powerful, but…

感谢作者的卓越贡献。我在此有两个小问题想请教您。
首先，rng无疑是可以考虑周期性条件的，这从选项的设置上就可以看出，但我还是想确认一下，对于npt模拟这种晶胞可变的动力学过程，rng会更新每步的晶胞信息吗？
例如，在dump格式文件中，包含每一帧的晶胞参数，程序是否会逐帧读取，还是只读取第一帧的参数。
当输入文件为XYZ这种不包含晶胞参数的…

Dear Hongkai,
Thank you for your very interesting research. Last half a year, I was aiming to solve the Helmholtz equation with PINNs using DeepXDE packages. I could reach a mean average percentage…

I wanted to implement a simple circular vector, and ended up finding major slowdown for accessing. Is this expected behavior:
```julia
using FFTViews
x = LinRange(-5,5,1000)
@btime x[200:800]

### Description of the enhancement or error report
No error message thrown when using a certain quasi-periodic mesh with tetrahedrons -- simulation just hangs in -opt, no console output, or in -dbg m…

Dear Mikael,
In the [MixedPoisson.py](https://github.com/spectralDNS/shenfun/blob/4faa1fbd364380dd52ff0bbce88f54e8d42bce08/demo/MixedPoisson.py#L1), I have two questions:
1 . How to modify it to …

## Reason
Meshes written by `--mesh-only` that contain split blocks from `BreakMeshByBlock` cannot be utilized for physical analyses with `InterfaceKernels` in a subsequent input file which reads the…

Gyroaverages may be crucial for providing a physical cut-off to the wavenumber spectrum required to be resolved in the moment_kinetics model.
Initial experiments implementing an ion gyroaverage is …
