**Is your feature request related to a problem? Please describe.**
We've been playing around with the new PRT model in MODFLOW 6. As a feature request, I was wondering if it would be possible to incl…

## Summary
The `fix emit/face ... region my_region` command should emit particles from everywhere on a box face that is within `my_region`. However, for certain values of Np (the exact number of pa…

This package works really well and it's super fast. I would like to request a feature that could enhance its utility in a common setup for 2D particle simulations: periodic boundary conditions (PBC), …

Parcels currently lacks automatic computation of the derivative of a `Field`. A use case is computing the gradient in a diffusivity field. In the `AdvectionDiffusion` kernels, this is now implemented …

## Summary
There is a segfault when running examples in the `track-surf-collisions` branch with image dumping uncommented. The examples run fine with the dump image section commented out.

**Describe the bug**
For the ISPH testcase, the domain is split into a 12x19 domain, however some particles are in cell {12,2} which can't exist.
**Expected behavior**
Particles should always be …

Hello,
I am trying to simulate a 3-dimensional magnetic disk (dot and or anti-dot type structure) lattice structure using Ubermag. I am mainly interested in stray field distribution. If it is a singl…

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…
