Many people are interested in simulating the "straightforward" and "cheaper" particle-based reaction-dynamics, i.e. no interaction energies, but diffusion and reactions between particles. This should …

When using GPU computation, the ID list in trackparticle seems to be reassigned based on the current position at each timestamp, while with CPU computation, particle IDs are inherited across different…

LP currently lacks a foundational implementation of fluid dynamics using the Smoothed Particle Hydrodynamics (SPH) method
_Note: PBF could be a consideration as well in early stages_

I'm using threads to run multiple minimisations in parallel and see segmentation faults. The LBFGS code _claims_ that it is thread safe, so maybe this is an issue with OpenMM, or the way that Sire is …

In superposition the grey streamlines and orange vector arrows appear at a much larger scale than the blue particles, and offset down and right. Screenshot attached. This issue occurs in Chrome, Firef…

**Is your feature request related to a problem? Please describe.**
Currently, of the three SPH codes in AMUSE (Fi, Gadget2, Phantom), only one (Fi) has a get_gravity_at_point function implemented, an…

**Description of the bug**
When combining pair lubricate/poly and pair brownian/poly to simulate the dynamics of a binary hard-sphere (HS) mixture, I find that there are strange attractions betwee…

At the moment, we can only take ranges with a step of 1, but it would be useful to reduce sets by taking steps of e.g. 10, 100 or 100.
Perhaps, we could extend the syntax to include something like …

When I add Lagrangian particles to the simulation, I also need to sample the model state along each Lagrangian trajectory. For example, I need a time series of vorticity, or maybe a passive tracer (o…
