Detailed Description

Accumulator for MPI-reduced boundary-face integrals.

Collects integrated quantities (e.g. force components, mass flux) over boundary faces on each MPI rank, then performs an MPI_SUM Allreduce to obtain global totals. The divisor div is reduced in parallel and can be used for area-weighted averaging.
