A new parallel subspace correction method for advection diffusion equation
A new parallel subspace correction algorithm is proposed to solve advection diffusion equation with mass conservative characteristic finite element (MCC FE) procedure. The dependence relations of the subdomains overlapping size, spacial mesh parameter, time step, iteration number with the convergence rate is analyzed, and the a priori error estimate of this parallel algorithm is given. Some numerical experiments are given to verify our theoretical result.
