Hi Matt<br>You can start experimenting by using<br>-pc_type hypre -pc_hypre_type boomeramg -help<br>which will give you all the boomeramg options.<br><br>When I use it I get intermittent segfaults, which I couldn't resolve with the Hypre guys, so good luck.

Hi,<br><br>i am trying to use boomeramg from hypre in petsc. What i am doing right now is<br>simply do:<br><br>m_ierr = PCSetType(m_pc,PCHYPRE);//CHKERRQ(ierr)<br>m_ierr = PCHYPRESetType(m_pc,"boomeramg");<br><br>
then i do my kspsetup etc...<br><br>i was wondering what other things i need to configure/set to properly use the<br>hypre preconditioner with petsc. This is new to me, so i am not really<br>experienced with this (that is using external packages through petsc). Also,
<br>these are the only hypre calls i found in the manual pages.<br><br>Maybe somebody with more experience can share some of their wisdom ..., or<br>point to a place where i can read up on it?<br><br><br>thanks<br>mat<br>
