'''Dissipative particle dynamics''' (DPD) is a technique originally developed for simulating hydrodynamic phenomena. In particular, it targets '''fluctuating hydrodynamics''', a mesoscopic regime in which fluctuations play a role. One of its main uses is a [[thermostats | thermostat ]] for [[molecular dynamics]] simulations, since the DPD interactions have the desirable property of momentum conservation (both linear, and angular). In [[Voronoi particles | one of its most recent formulations]] it makes intense use of [[ Voronoi cells | Voronoi tessellations ]].

Dissipative particle dynamics (DPD) is a technique originally developed for simulating hydrodynamic phenomena. In particular, it targets fluctuating hydrodynamics, a mesoscopic regime in which fluctuations play a role. One of its main uses is a thermostat for molecular dynamics simulations, since the DPD interactions have the desirable property of momentum conservation (both linear, and angular).

Some works have been able to link this technique and DPD, thus creating the "SDPD method". Another formulation makes intense use of Voronoi tessellations .
