We study the collective flow of open charm mesons and charmonia in Au+Au collisions at √(s)=200 GeV within the hadron-string-dynamics (HSD) transport approach. The detailed studies show that the coupling of D,D mesons to the light hadrons leads to comparable directed and elliptic flow as for the light mesons. This also holds approximately for J/\ensuremathΨ mesons since more than 50% of the final charmonia for central and midcentral collisions stem from D+D induced reactions in the transport calculations. The transverse momentum spectra of D,D mesons and J/\ensuremathΨ's are only very moderately changed by the (pre-)hadronic interactions in HSD, which can be traced back to the collective flow generated by elastic interactions with the light hadrons.
