    "abstract": "We investigate the influence of the real part of the in-medium pion optical\npotential on the pion dynamics in intermediate energy heavy ion reactions at 1\nGeV/A. For different models, i.e. a phenomenological model and the\n$\\Delta$--hole model, a pionic potential is extracted from the dispersion\nrelation and used in Quantum Molecular Dynamics calculations. In addition with\nthe inelastic scattering processes we thus take care of both, real and\nimaginary part of the pion optical potential. A strong influence of the real\npionic potential on the pion in-plane flow is observed. In general such a\npotential has the tendency to reduce the anticorrelation of pion and nucleon\nflow in non-central collisions.",
