<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></div></div></blockquote><div><br></div><div>Yes (although I do not see ILU in their docs). You can see all the BoomerAMG options with -help.</div>
<div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div bgcolor="#FFFFFF"><div><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></blockquote><div><br></div><div><a href="http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Sys/PetscOptionsSetValue.html">http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Sys/PetscOptionsSetValue.html</a></div>
