**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 SPH, thus creating the "SDPD method". Another formulation makes intense use of Voronoi tessellations .
