collide¶
An MPCD collision method is required to update the particle velocities over time. Particles are binned into cells based on their positions, and all particles in a cell undergo a stochastic collision that updates their velocities while conserving linear momentum. Collision rules can optionally be extended to also conserve angular momentum The stochastic collisions lead to a build up of hydrodynamic interactions, and the choice of collision rule determines the transport coefficients.
