move_style sphere brownian move_style circle uniform
Set one or more options that determine how particles move in a spatial simulation.
The cube option means particle will sample points in a small cube around their locations. The sphere option means particles will sample points in a small sphere around their location.
The square option means particles will only move in 2d and sample points in a small xy square around their locations. The cirlce option means particles will only move in 2d and samples points in a small xy circle around their locations. These options can be used with a global simulation domain that is small in the z-dimension to effectively setup a 2d simulation.
The uniform option means the sampling of volumetric (or planar) space is uniform. The brownian option means the sampling is from a Gaussian so that particles move in Brownian motion.
For 2d particles diffusing on regions or triangulated surfaces, only the uniform/brownian options are relevant since particles always effectively move in 2d, sampling within a circle tangential to the surface.
This command can only be used for spatial simulations.
