  Recent experimental results revealed large elliptic flow of the charmed
hadrons at LHC energies, unexpectedly similar to that of the charged pions. The
mentioned measurements are often interpreted using transport models, which
incorporate dissociation and recombination mechanisms for charm quarks. In this
report, a modified version of the Monte Carlo model with string repulsion is
used to calculate azimuthal correlations with charmed hadrons. The string
repulsion mechanism may provide significant angular correlations and can be
considered as an alternative to thermalization picture.
