PCGAMGSetCoarseEqLim - Set maximum number of equations on coarsest grid </blockquote><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Is there a way to set the minimum number of equations on the coarse grid also? This particular case goes down to 6, 54 and 642 unknowns on the coarsest grids when I'm guessing it would be better to stop at 642 unknowns for the coarsest level. <br></blockquote><div><br></div><div>No, because I don't know how it is going to coarsen I did not want to bother with backtracking (I do when there is an error on the coarse grid so it would be easy to add this but I don't think it is worth the clutter). </div><div><br></div></div></div>
