inline

Perform the actual swept moments computation for the given cell.

After decomposing the cell into faces, it constructs a swept polyhedron for each face such that we have a positive volume if its centroid lies outside the cell (and hence attached to an incident neighbor) and a negative volume otherwise (and hence attached to the source cell). The sign of the computed moments are actually related to that of the fluxes associated to each face of the cell, and are computed using the divergence theorem. To avoid degenerated cases and to limit the loss of accuracy in case of large displacements, we perform a quick check on the volume of each swept polyhedron such that they don't exceed a certain threshold. Notice that the stencil is not really required but still kept to be consistent with the other intersection functors.

Parameters

target_id	the current target cell index.
stencil	current source cell and its immediate neighbors.

Returns

a list of swept region moments and related source cell pair.
