Query: Invariance of experimental observables with respect to coarse-graining
  in standard and many-body dissipative particle dynamics   Dissipative particle dynamics (DPD) is a well-established mesoscale
simulation method. However, there have been long-standing ambiguities regarding
the dependence of its (purely repulsive) force field parameter on temperature
as well as the variation of the resulting experimental observables, such as
diffusivity or surface tension, with coarse-graining (CG) degree. Here, we
revisit the role of the CG degree and rederive the temperature dependence in
standard DPD simulations. Consequently, we derive a scaling of the input
variables that renders the system properties invariant with respect to CG
degree, and illustrate the versatility of the method by computing the surface
tensions of binary solvent mixtures. We then extend this procedure to many-body
dissipative particle dynamics (MDPD) and, by computing surface tensions of the
same mixtures at a range of CG degrees, demonstrate that this newer method,
which has not been widely applied so far, is also capable of simulating complex
fluids of practical interest.
