Potential calculation

The planetary potential can be softened over a length that scales either with the disk pressure scale height or with the planetary Hill radius. In addition, the force acting back onto the planet can disregard a fraction of the Roche lobe content. Finally, an initial tapering can be applied to slowly turn the planet mass on.

  • MassTaper

    "Turn-on" the planets slowly

  • ExcludeHill

    Discard a fraction of the Roche lobe in the torque calculation

  • RocheSmoothing

    The planet’s potential is softened over a length that scales with the Hill radius

  • ThicknessSmoothing

    The planet’s potential is softened over a length that scales with the disk thickness

  • IndirectTerm

    Specify whether the frame acceleration is applied to the disk
