Currently, `UpdateCellList!` clears all cells and adds particles again. For use cases like SPH simulations where only small changes in position happen between updates, it will be much faster to only u…

## Goal
* The goal is, to have a virtual particle at the center of mass of a bunch of other particles (say, a molecule).
* Forces acting on this center of mass are distributed back onto the const…

## Description
There's been some recent (and IIRC, previous) discussion around adding cell importance. I'm creating this issue as a place for that discussion and for the placement of motivating use…

It would be nice to be able to vary the number of particles we try to spawn in each cell over the simulation.
This would allow an increased number of samples in regions of interest while keeping th…

In typical FBPIC simulation, the timestep is small enough that particles cannot travel beyond `n_guard/2` during a single timestep, so that they always remain with the local subdomain.
However, it…

To my understanding, the FFT can be refactored furhter:

The FFTBackend currently calls the halo communication before/after the FFT.

Hi all,
I'm trying to scale up an electrostatic simulation to mu…

Running step-70 works just fine, but only just so :-)
In writing #15370, I spent a quality hour discovering the following. In the default input file, `parameters.prm`, we have
