<html><head></head><body bgcolor="#FFFFFF"><div></div><div>Hei!<br><span>I was going through the Petsc user archives when I came across a</span><br><span>discussion with Barry Smith regarding use of BoomerAMG through Petsc</span><br>
<span>(<a href="http://lists.mcs.anl.gov/pipermail/petsc-users/2006-October/000692.html">http://lists.mcs.anl.gov/pipermail/petsc-users/2006-October/000692.html</a></span><span>).</span></div><div><br><span>What I did understand from that is some of the Hypre options cannot</span><br>
<span>be accessed through Petsc. But options like Pilut are available as preconditioners or solvers depnding on ksptype.</span><br><span>I am trying to use ILU smoothening to BoomerAMG (Hypre's manual lists the smoothers available and the function calls</span><span>). The questions that remain after going through that discussion are:</span><br>
<span></span><br><span>1. Can a smoothening option in hypre's boomerAMG could be chosen at all using Petsc?</span><br><span>2. Could the function calls phrases used in Hypre itself be somehow employed in the Petsc code?</span><br>
<br>Would be really grateful for any advice. Since I am using an IDE to build the code, non-command line option tricks would also be of great help.</div><div><br>Arun Kamath<div>NTNU Trondheim</div></div></body></html>
