Abstract

This work introduces the Locally Filtered Transport (LFT) method
for numerical transport models. Locally turning off the transport
computation in areas of nearly uniform concentration is proposed as a
new approach for reducing computational cost in ecosystem models that
require transport of tens to hundreds of constituent concentrations. The
proposed method is locally mass conservative just as the discontinuous
Galerkin finite element scheme it is based on. The performance of the
method is illustrated using numerical examples including an
advection-reaction ecosystem simulation with a simple nitrogen, phytoplankton, and zooplankton (NPZ) model.
