AB - <p style="text-align: justify;">The numerical solution of large scale multi-dimensional convection diffusion
equations often requires efficient parallel algorithms. In this work, we consider the extension of a recently proposed non-overlapping domain decomposition method for two
dimensional time dependent convection diffusion equations with variable coefficients.
By combining predictor-corrector technique, modified upwind differences with explicit-implicit coupling, the method under consideration provides intrinsic parallelism while
maintaining good stability and accuracy. Moreover, for multi-dimensional problems,
the method can be readily implemented on a multi-processor system and does not have
the limitation on the choice of subdomains required by some other similar predictor-corrector or stabilized schemes. These properties of the method are demonstrated in
this work through both rigorous mathematical analysis and numerical experiments.</p>
