For style dpd, the pairwise energy associated with style dpd is only due to the conservative force term Fc. The pairwise virial is calculated using all 3 terms. For style dpd/tstat there is no -pairwise energy or virial. +pairwise energy, but the last two terms of the formula make a +contribution to the virial.
For style dpd, the following coefficients must be defined for each pair of atoms types via the pair_coeff command as in diff --git a/doc/pair_dpd.txt b/doc/pair_dpd.txt index e892511150..8003384c53 100644 --- a/doc/pair_dpd.txt +++ b/doc/pair_dpd.txt @@ -66,7 +66,8 @@ value from Tstart to Tstop.
