force¶
MPCD can apply a body force to each MPCD particle as a function of position.
The external force should be compatible with the chosen
Geometry. Global momentum conservation can be
broken by adding a body force, so care should be chosen that the entire model
is designed so that the system does not have net acceleration. For example,
solid boundaries can be used to dissipate momentum, or a balancing force can be
applied to particles that are embedded in the MPCD particles through the
collision step. Additionally, a thermostat will likely be required to maintain
temperature control in the driven system.
