ExcludeHill
When this parameter is set to YES,
a cut-off is introduced when estimating the torque of the disk on any
given planet, as follows:
The torque T of any zone
(interior or exterior to the Roche lobe) is multiplied by 1-exp[-(d/Rh)2] (where
d is the zone center distance
to the planet and Rh
the planet Hill radius).
Note that the torque files 'tqwk[i].dat'
contain both the torque values with and without cut-off, regardless of
the value of ExcludeHill.
When ExcludeHill is set to
NO, the torque without cut-off is applied to the planet to update its
velocity, while when ExcludeHill is
set to YES, the cut-off torque is applied to the planet. Defining ExcludeHill therefore only makes
sense if the simulated planets are migrating. If they are not (i.e. if
they are on fixed circular or eccentric orbits), the outcome is
independent of ExcludeHill.
This parameter should not be confused with the parameters related to
the smoothing length (RocheSmoothing
and ThicknessSmoothing)
