**Describe the bug**
When you run the same simulation repeatedly, the new particles are just added to the end of the existing phase-space, and the header is updated to correspond only to the new part…

Hello, I am a beginner. Could you please tell me if Fluid X3D can realize my idea: to create a rectangular box, define a velocity on the side of the box to simulate wind blowing, then draw a small hol…

I was recently testing out the new MPCDF "viper" machine by running small-box simulations along the lines of [this paper](https://arxiv.org/abs/2312.06763), using the most up-to-date version of the co…

For context, I ran several simulations inside a loop, varying mass composition to see the energy spectrum at the Earth. I noticed that the RAM consumption was exceedingly high after some time. Further…

To efficiently particle files, we need to know the total number of particles.
Currently, that means we load every file once before in order to allocate space in the resulting file (which can be ver…

### Proposed new feature or change:
The local density in particle simulations is calculated at the locations of the particles but in cases where there MIPS is collapse-like, this causes a sometimes u…

A recent restructuring of the OpenMM section of nanover-protocol means that the python server behaves more like the rust server (in that the data from the simulation is retrieved via .getState rather …

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…

Hi! I've put together a little benchmark of doing some good old 90s particle simulations: https://github.com/ocharles/reactive-banana-fireworks-benchmark.
Essentially every clock tick I spawn a new p…
