Abstract

IllinoisGRMHD and HydroBase variables are incompatible; The former uses 3-velocity deﬁned as $v^{i} = u^{i} ∕ u^{0}$ , and the latter uses the Valencia formalism deﬁnition of $v^{i}$ .

Deﬁne the Valencia formalism’s deﬁnition of $v^{i}$ to be ” $W^{i}$ ”, and IllinoisGRMHD’s deﬁnition ” $v^{i}$ ” Then
