Title:
An algebraic variational multiscale-multigrid method based on plain aggregation for convection-diffusion problems 
Abstract:
A new computational framework referred to as algebraic variational multiscale? multigrid method is proposed, representing the initial step of our work on merging the variational multiscale method with algebraic multigrid projection methods. This new approach allows for a separation of resolved scales into various scale groups in a purely algebraic way, that is, with no need to utilize further discretizations beyond the basic one. By this means, it conveniently facilitates the application of...    »
