A Lagrangian advection scheme with shape matrix (LASM) for solving advection problems
solving advection problems Lagrangian advection scheme
2014/12/19
A new Lagrangian advection scheme with shape matrix (LASM) is proposed to take advantage of the extreme low numerical diffusion of the Lagrangian methods. The tracer is discretized into finite parcels...
