Hi all,

Can anyone point me to a quantitative explanation of the geometric multigrid and Vanka smoothers? I found a qualitative article describing the GMG smoother, but it doesn't quantify how much it reduces the cost of a problem. I have found nothing yet on the Vanka smoother except that it is specialized for the incompressible Navier-Stokes equations and that it might be used for handling zeros on the diagonals of a sparse matrix. Any sources or summaries you have are much appreciated!

Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
